gedit assert failure: *** stack smashing detected ***: /usr/bin/gedit terminated

[zob]

Gedit from Gnome3 staging crashes when pressing CTRL+SHIFT+I on this system (whatever that is supposed to do).
It does it every time. To reproduce:
1 Open gedit
2 Press CTRL+SHIFT+I
3 Crashes immediately

Running ubuntu-gnome 14.10 fully updated, kernel 3.16.0-23-generic

Gedit is the staging version 3.14:

ctl-shift-I launches the gtk+ inspector, but only if you have libgtk-3-dev installed. Without that it should do nothing

Also it seems you have git snapshots of gtk 3.15 installed (via ricotz/testing), does it still happen if you purge that ppa?

I just got these updates (among them is libgtk-3.0) and it seems to be fixed. At least I can't make it crash with CTRL+SHIFT+I anymore:

Just for testing purposes I then installed libgtk-3-dev with these new versions and tried CTRL+SHIFT+I, which now should open the gtk+ inspector. Unfortunately it now crashes with libgtk-3-dev (3.15.1+git20141031.00f618ea-0ubuntu1~14.10~ricotz0) installed.

[zob (zob)]

I now purged the gnome 3 ppa and back at version 3.12.2-0ubuntu15 of libgtk-3-0 nothing crashes, neither without libgtk-3-dev installed nor without.
I should add that gtk+-inspector does not open. In fact CTRL+SHIFT+I does nothing. However it doesn't crash anything. So that bug is for the ricotz version only.
