Apparently, no debug symbols for the libraries in question were found, so I only got this small backtrace for the crash which occurs every time I'm adding a System Tray widget to a panel; plus, plasmashell appears to hang for 1-2 minutes after restarting, eventually displaying the panel and widget. Application: plasmashell (5.4.2) Qt Version: 5.4.2 Operating System: Linux 4.2.0-16-generic x86_64 Distribution: Ubuntu 15.10 Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
