Application: plasmashell (5.14.5) Qt Version: 5.11.3 Frameworks Version: 5.54.0 Operating System: Linux 4.19.0-5-amd64 x86_64 Distribution: Debian GNU/Linux 10 (buster) -- Information about the crash: Often, but not always, after I resume from suspending the system, Plasma crashes after I introduce my password to unlock the screen. When this happens, I get an "xmessage" window with the following error: "Could not start ksmserver. Check your installation.", and Plasma reloads. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
