Application: kwin_x11 (5.8.7) Qt Version: 5.6.2 Frameworks Version: 5.32.0 Operating System: Linux 4.4.114-42-default x86_64 Distribution: "openSUSE Leap 42.3" -- Information about the crash: I am Running Plasma KDE 4.14.33, which came with OpenSUSE Leap 42.3 on a HP TouchSmart Model IQ840 Desktop PC, equiped with an Intel Core 2 Duo CPU, 4 Gigs DRAM, 500 Gigs HD and Nvidia GeForce 9300 GS Graphics System. I am using the Nvidia Graphics Driver, which is included with OpenSUSE Leap 42.3 and all of the standard applications that came with this distribution. I have been using this system for about three months now with hardly a problem until today when I started the system and it booted up fine up to after I login to my own user account. Then Plasma KDE crashed for some reason. The system was shutdown correctly before this session. The crash can be reproduced sometimes. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
