Could you install the xulrunner-1.9.1-dbg and gdb packages , run iceweasel -g, type run at the gdb prompt, and when it is sucking the 100% cpu, ctrl+c, which should bring the gdb prompt back, and then type bt full and send the output here.

Bug#556914: [iceweasel] after closing, iceweasel process remains active and using 90% CPU
reassign 556914 kdebase-runtime subscribe 556914 gland...@debian.org thanks Thanks. So here is what seems to be happening: the oxygen kde plugin has a destructor function that does some cleanup, during which it needs to send some requests to the X server to free pixmaps. Except that by the time you reach there, the connection to the X server is long gone. So the poll() call returns an error and is retried indefinitely. It seems to me the problem lies in the oxygen plugin, which shouldn't be doing this, but it could also very well be lower in the stack. It could be interesting to see what exactly is retrying to poll() indefinitely, because that could be a separate bug, too. I'll leave the rest of the investigation up to the kdebase-runtime maintainer(s) (that is the package holding the oxygen plugin), but I'm staying subscribed to this bug out of curiosity (and if help is needed, I'm here, too ;) ).

Bug#556914: [iceweasel] after closing, iceweasel process remains active and using 90% CPU
I think I found what the problem was... I changed in KDE settings that GTK apps don't use KDE theme and colors. After that I tried Iceweasel several times and never had CPU jam at 100% after closing the Iceweasel's window So I think problem is not with Iceweasel but coexistence with KDE desktop environment. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
