unfortunately my gedit is unusable, since every time i try to open a text file, it crashes.
here the terminal message
the last thing i (regret) did before the problem appeared, was enabling the dialog of the source code browser plugin
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)
any help would be very appreciated!! thanks!
