Bug ID: 361104 Summary: Plasma crashed after switching virtual desktop via application shortcut and then switching back Product: plasmashell Version: 5.5.4 Platform: Ubuntu Packages OS: Linux Status: UNCONFIRMED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: nik_1...@mail.ru CC: bhus...@gmail.com, plasma-b...@kde.org Application: plasmashell (5.5.4) Qt Version: 5.5.1 Operating System: Linux 4.4.0-15-generic x86_64 Distribution: Ubuntu Xenial Xerus (development branch) -- Information about the crash: - What I was doing when the application crashed: I have Thunderbird shortcut in my task manager. I started it on virtual desktop 2. While I was on virtual desktop 1 I clicked on that shortcut and desktop switched to 2-nd to Thunderbird. Then I immediately clicked on 1-st desktop in task manager. Desktop had swithed but task manager freezes for about 1 second and crashes. 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".
