#1126 Fluxbox crashes sporadically
Fluxbox crashes when I'm not even at my computer. The only other program running is pidgin-2.10.10 . It may be related. A backtrace is pasted below:

Diff:
Segfaults because of trying to exit on XIOerror (no good idea, see eg. https://bugs.kde.org/show_bug.cgi?id=112960#c12 )
Question remains on why ther IOError occurred itfp.
Usually this means the X server crashed.
If this is still a problem, one should check on that.
=> Did the X server survive those crashes?
Otherwise the bug can more or less be closed.
Crashing in return of an XIOerror (for an X11 crash) isn't nice, but not a critical bug per se (the problem is the crashing X server, it takes fluxbox down anyway - whether the latter segfaults or not)
I don't leave my computer on all the time anymore, so I don't really know
if it still happens. Also, my git checkout is so old that it wouldn't give
any valuable information. However, it definitely did not result from an X
server crash, since it was still running after these crashes (my
.fluxbox/startup restarts fluxbox when it crashes).
Thanks for all the recent work!

Bugs: #1126
Then the server cuts the line because of an assaulting request from fluxbox (typically HUUUUGE image upload, but could plenty of things)
Interestingly, this seems to happen when some client goes urgent - from the description (and by its nature) this will be pidgin.
Does this cause trouble?
(I've no idea whether pidgin is WM_CLASS for pidgin, so ensure this really sets the client urgent)
The used theme might be of relevance as well.
And the "DemandsAttentionTimeout" value in your ~/.fluxbox/init =)
