#1082 Geany regularly crashes and fatally hangs on Lubuntu 14.04.1 x64
Hi, Geany has regularly been crashing/hanging on a white page for me on Lubuntu 14.04.1 x64. I'm using i3WM if that matters, on an Intel Thinkpad X61s. I don't have a lot of software installed.
It works for a few hours just fine, but invariably crashes. It usually crashes while it is in the background, not while I am actively using it. It seems to only happen on Lubuntu, not Ubuntu itself. It's happened around 15-20 times now for me. Oddly, it used to simply crash (I would switch to Geany's workspace and find nothing there); now it hangs with an all white screen and can't be brought to life.
This happens in the Geany included in lubuntu repositories (1.23.1 I think), as well as the 1.24.1 included in Geany's repository.
I've been editing PHP files.
I love Geany, it's head and shoulders my favorite Linux editor, but this has made it almost unusable.
Thank you,
Sasha Shepherd

IIRC we had reports in the past that were due to bugs in i3. But it leading to a full crash is odd. Maybe you could try with another WM and see if the crash still occurs?
This suggests it's a problem with something specific to Lubuntu, either breaking or breaking Geany.
This is actually not so odd, if something weird leads to a crash it's likely to be memory corruption or similar, and in this case anything can happen (crash, hang, or even nothing at all).
Thanks for this. However, could you produce a new backtrace after installing the debugging symbols of the various libraries? (libgtk2.0-0-dbg, libglib2.0-0-dbg, and possibly others like Pango, Cairo or X11 -- and ideally Geany's, but I'm afraid they aren't available in the repositories)
