gedit crashes when opening any file

[fruitz]

hi all.

unfortunately my gedit is unusable, since every time i try to open a text file, it crashes.

here the terminal message

TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
**
ERROR:/build/buildd/pygobject-3.4.0/gi/_gobject/pygobject.c:946:pygobject_new_full: assertion failed: (tp != NULL)
Aborted (core dumped)

the last thing i (regret) did before the problem appeared, was enabling the dialog of the source code browser plugin

https://github.com/Quixotix/gedit-source-code-browser

any help would be very appreciated!! thanks!

try moving out the files in
~/.gconf/apps/gedit-2
or
~/.config/gedit

[fruitz]

there is no folder named
~/.gconf/apps/gedit-2
and even after removing the folder
~/.config/gedit
and rebooting nothing is solved.

check output from

find ~/ -iname gedit*

Have you tried a purge and reinstall?

sudo apt-get remove --purge gedit

sudo apt-get autoremove

sudo apt-get install gedit

francesco@francesco-wimdu:~$ find ~/ -iname gedit*
/home/francesco/Downloads/geditpycompletion-master.zip
/home/francesco/.local/share/gedit
/home/francesco/.local/share/Trash/files/gedit

/home/francesco/.config/gedit

purging and reinstalling didnt do the trick

am not sure so wait for someone else to comment but the next step I'd take is

sudo mv /usr/share/glib-2.0/schemas/org.gnome.gedit.plugins.sourcecodebrowser.gschema.xml ~/Desktop/

glib-compile-schemas /usr/share/glib-2.0/schemas/

yes. tried it. same error when opening file

ERROR:/build/buildd/pygobject-3.4.0/gi/_gobject/pygobject.c:946:pygobject_new_full: assertion failed: (tp != NULL)
Aborted (core dumped)

Create a new user on the host and login as that user, then run/check gedit.
Same issue, or no issue?

[fruitz]

good point. the problem is only with my account apparently

Are you 100% sure there's no ~/.gconf/apps/gedit-2 directory? It should exist.

One more place to look for rogue files is ~/.local/share/applications. You might find some files named gedit-#.desktop. They should be harmless, but that's all I can think of for an issue only affecting 1 user.

Another very unlikely culprit is ~/.config/gnome-panel/launchers, which might have another gedit.desktop, if you have a panel launcher for gedit. Again, I don't think this should pose a problem, but it's somewhat possible.
