Dolphin file manager won't start

[Nikuro]

Hello! Faced such a problem. When I try to open the Dolphin folder, it crashes. The error handler has the following error:

Application: Dolphin (dolphin), signal: Segmentation fault

Before that, everything worked fine, the error began to appear spontaneously. Tried reinstalling, doesn't help. Help please, I have no idea what's wrong!

Try deleting the dolphin file inside /home/username/.config/session/
it is a hidden file
reboot
should right a new one when it reboots

Keep that list of errors. Then, I would use Synaptic, or apt, or dpkg to purge Dolphin completely. Once it's purged, check for the existence of those files, and manually remove any that still exist. Then install it. Reinstalling over the existing package of software does not always resolve issues at the library module level.

Hello! Faced such a problem. When I try to open the Dolphin folder, it crashes

What distro? If not a KDE distro, i.e. Kubuntu, KaOS, Did you install dolphin on your own? How did you install it?

Try deleting the dolphin file inside /home/username/.config/session/

I have it on ~/.configkde and there's also a dolhinrc file in there. This on KDE5.

Then, I would use Synaptic, or apt, or dpkg to purge Dolphin completely

If this is a KDE distro; Kubuntu, KaOS, dolphin is quite hard-corded into the desktop and attempting to remove might remove the whole DE. For instance, here in Debian running on KDE I get:

$ sudo apt-get remove dolphin
the following packages will be REMOVED:
dolphin kde-baseapps kde-plasma-desktop konqueror

If I chose "Y" instead of "N", I would end up with a broken system with no DE at the very least. So removing dolphin might just be a bad idea.

Which can be installed from the command line.

A re-install did not work, on a fundamental component.

So onto the next solution.

Also:

I have it on ~/.configkde and there's also a dolhinrc file in there. This on KDE5.

That's a distro specific configuration. In Kubuntu, I do not have a ~/.configkde, it's ~/.config/dolphinrc

Thanks a million, mate, that just saved my life on KDE NEON DEC2020

Just wanted to say thanks, deleting the dolphin file inside /.confg/session/ worked for me.

Just a note on the above for all the Viewers.

On every Linux I have tried (100 +), with every combination of FM (File Manager) and DE (Desktop Environment), the FM and the DE are inimately and intricately tied together.

So for the "majors", the DEs and FMs are as follows:

GNOME - Nautilus (aka Files)

MATE - Caja

Cinnamon - Nemo

KDE - Dolphin

Xfce - Thunar

So if you delete or purge Nautilus, Caja, Nemo, Dolphin, or Thunar you will BREAK GNOME, MATE, Cinnamon, KDE or Xfce.

Cheers

BTW have a current Timeshift snapshot in place before you try anything like this.

If an OOTB made distro; everything is installed and configured by the devs and not the user who just install and use without modifying and/or installing anything else, then yes, but say you install from a netinstall.iso and then add XFCE and dolphin as FM, removing dolphin won't remove or break XFCE. This is why asked if this was or not a KDE distro and if OP had installed dolphin on his/her own.

And forgot XFCE - Thunar

Whoops - thanks Lord Boltar, edited.

And forgot XFCE - Thunar

Actually, removing thunar from XFCE4 won't break it, I just tried in one VM out of curiosity because I kind of remembered it not being pulled as a dependency while installing XFCE4 and as a matter of fact I had to explicitly install it otherwise it wouldn't. This is what I got when tried removing thunar from my Linux Lite VM:

$ sudo apt-get remove thunar
The following packages will be REMOVED:
   thunar thunar-archive-plugin thunar-media-tags-plugin thunar-volman
2,724 kB will be released after this operation

So it seems thunar might be an exception to the rule, and it's not as hard-coded as others into the DE.

Thunar does not seem to be an exception with Zorin OS Lite and it's XFCE desktop. This looks like it will be a disaster if I allowed it to happen.

[EDIT] But it was not a disaster when tested in a VM. I got the same response as below, and Thunar was removed, but Zorin Lite continued to work otherwise, as far as I can tell. So @Tolkem may be right, and XFCE/Thunar may well be an exception. [/EDIT]

Try
Settings >Configure Dolphin > Services > Uncheck "the link to activities"

Just a heads up at this point, namely that the OP has not been since for 13 days since first Posting, so either he is/has

1. Gone elsewhere in search of answers
2. Found a solution
3. Found the discussion above somewhat daunting
4. Lost interest
5. Other

Just thought I'd say.

Having said that, I have been engaged in some testing and will reveal more between now and next year.

One preview to that is

Don't try to remove the Nemo FM from a Cinnamon Distro, you will brick your Distro.

Fixed this, of course, with a Timeshift restore
