this crashes *before* actually choosing an alternative? Yep, it's weird, happens as soon as I select the menu item. Is there a log that might have some add'l info? Application: plasmashell (5.9.90) Qt Version: 5.7.1 Frameworks Version: 5.31.0 Operating System: Linux config-4.10.0-2-generic x86_64 Distribution: Ubuntu Zesty Zapus (development branch) -- Information about the crash: - What I was doing when the application crashed: Right click on the Panel start icon (KDE icon) Choose "Alternatives" from the context menu The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
