[Sebastien Bacher (seb128)]

thank you for your bug report, the issue is in python code which gedit doesn't use by default, do you use some extra option using it?

[Sebastien Bacher (seb128)]

seems similar to bug #863773

[Marc Deslauriers (mdeslaur)]

I use some gedit plugins which are in python, including the snippets plugin, so it's probably a dupe of #863773.
