Description Adrian Wannenmacher 2019-06-21 22:06:02 UTC

Application: plasmashell (5.16.1)

Qt Version: 5.12.4
Frameworks Version: 5.59.0
Operating System: Linux 5.1.11-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I just logged into my system and wanted to start an application from the default application launcher. When I pressed the meta key the first time, the background of the menu appeared first and then the application icons and names slowly faded in. As I didn't expect that to happen, I decided to press the button two more times to reopen the menu and it seemingly worked. But when I pressed the button again to close the menu, plasma crashed.

After a crash plasma is automatically restarted. If its the first restart, I can trigger the crash like I described before. If its the second restart, the menu doesn't appear any more. The only thing that happens is that a blue litte bar appears (or disappears) above the icon to indicate that its active. I also can't trigger the crash any more.

I tried to re-login and to restart the system, but plasma keeps crashing if i press the meta key four times is a short period of time.

I also tried what happens if I press the button with some distance between each hit and in that case plasma doesn't crash.

The crash can be reproduced every time.
