Application: plasmashell (5.4.2) Qt Version: 5.5.1 Operating System: Linux 4.2.0-1-amd64 x86_64 Distribution: Debian GNU/Linux testing (stretch) -- Information about the crash: - What I was doing when the application crashed: I was trying to login! Before, I was logged in, and my system hanged while I was playing some music. On reboot, sddm would not come up - it would hang, essentially. I replaced it with lxdm and that worked. However, trying to login to a KDE session, I was met with severa crash notifications, no window manager and no panel. Other apps can start, e.g. Iceweasel, konsole etc. - Unusual behavior I noticed: Like I said, it's after a hard reboot during a hang. Probably there's a problem dealing with partially corrupt data files written to during runs. But - what are they? And why a crash rather than a graceful failure? The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Can I see ~.xsession-errors please
Created attachment 95397 [details] .xsession-errors from a session with crashes So, here's an .xsession-errors I generated just now; obviously it's not the same session as the crash reports I uploaded a before. If it's critical for the reports and the .xsession-errors to be from the same session, let me know. Also note that this session was started using LXDE. If I try to use sddm - the machine hangs. Finally I'll note that the machine has an NVIDIA GTX 650 Ti - although the display does not use it - and a few days ago I installed CUDA 7.5 and the display drivers which come with it. I was thinking perhaps that could be part of the cause.
> was thinking perhaps that could be part of the cause. It is, the error was in us using OpenGL. I just wanted to get the exact error message from this log for our error handling.
