Created attachment 87424 [details] New crash information added by DrKonqi konsole (2.13) on KDE Platform 4.13.0 using Qt 4.8.6 The kind of crash was "just like the duplicates". I'll add what I can about the history of the konsole process that crashed, just in case it helps to investigate some thread state mess up issue: Konsole crashed, when I was closing one of two konsole terminal windows on the current virtual desktop, with about five more terminal windows open on other virtual desktops of a 4 by 4 compiz desktop wall. All the terminals were part of the same konsole instance. This instance had been running since seven days. As I have the habit of doing small independent shell tasks in a newly opened terminal, which I'll close after the short task, the konsole process had handeled quite some new windows, while there were very few terminal tabs used. I use unlimited scroll back buffers, and while I did not obviously run programs with much output (in rate, or total volume), the long-running windows could have collected a lot of scrollback over that week (I had the buffer reset one time on a single window). I use a 4GB tmpfs for /tmp; did not notice any file-system full indications, but I think it happened before that console tmp files filled the tmpfs. -- Backtrace (Reduced): #6 0x00007f84b365c08a in QApplication::x11ProcessEvent (this=0x7fffff496f30, event=event@entry=0x7fffff496a30) at kernel/qapplication_x11.cpp:3529 #7 0x00007f84b3684b02 in x11EventSourceDispatch (s=0x1798a00, callback=0x0, user_data=0x0) at kernel/qguieventdispatcher_glib.cpp:146 [...] #11 0x00007f84b42767be in QEventDispatcherGlib::processEvents (this=0x16c0af0, flags=...) at kernel/qeventdispatcher_glib.cpp:436 #12 0x00007f84b3684bb6 in QGuiEventDispatcherGlib::processEvents (this=<optimized out>, flags=...) at kernel/qguieventdispatcher_glib.cpp:204 #13 0x00007f84b42480af in QEventLoop::processEvents (this=this@entry=0x7fffff496e00, flags=...) at kernel/qeventloop.cpp:149
