Description Jean-François Fortin Tam 2014-04-06 01:38:34 UTC 
I'm not is a position to try out Gedit 3.12 for the time being, but I encountered a crasher with 3.10 and since those are pretty rare I thought it would be good to report it:

Hi, work for me in 3.12 with your samples.
It will be great if you find a way to try with 3.12 too.

I can now reproduce this in 3.12 (from the Fedora 20 COPR). I just extracted those two files to /tmp/, opened them up with gedit, and tried to "tear off" one of the tabs.

I get a bunch of these before the segfault:

Actually bug #739510 is a dupe of this. Description/repro instructions:

Opening my Pitivi 0.94 release notes text file, if I tell gedit to move that document tab to a separate window, or if I open two gedit windows and load that document, gedit crashes like trace #234291

Created attachment 289800 [details]

And here's a video demonstration of how to trigger the crash from the perspective of bug #739510.

Hi,

You seem to have an old gedit-code-assistance plugin triggering this error, please retry after deactivating it.






Comment 8


Jean-François Fortin Tam





          2014-11-04 04:00:33 UTC
        



Indeed, disabling the code assistance plugin (funny: it segfaulted gedit immediately when you deactivate it!) made tabs tearoff work without segfaulting now.

Does that mean it's fixed in 3.14?

It mean that it's a gedit-code-assistance fault which has been re-written since,
so if you want to use gedit-code-assistance, get the last version which need gnome-code-assistance and some dependencies for the backends.
