Bug ID: 382773
Summary: Global Menu consistently crashes the KDE desktop
Product: plasmashell
Version: 5.10.4
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: paul.mccom...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.10.4)
Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-27-generic x86_64
Distribution: KDE neon User Edition 5.10
-- Information about the crash:
- What I was doing when the application crashed:
This has happened with multiple apps including but not limited to Discover and
Min (a browser). Although, I have noticed that Dolphin does not have this
problem. What happens is that I open an application, I decide to click on an
option from the Global Menu like file or edit, an outline of the dropdown menu
appears and freezes in place, then the desktop, the panels, and the widgets all
disappear and KDE Plasma crashes leaving a black background. The apps
themselves, however, are fully functioning allowing me to use them and drag
them around the black desktop with complete animations. Often KDE Plasma
restarts after 5 or so seconds, but rarely I do have to logout and re-log back
in to start up the desktop again. In other cases, I have noticed the Global
Menu to be unresponsive to any user interaction and therefore giving no
possibility for KDE Plasma to crash, but for this specific issue I'm reporting,
it is in relation to a full KDE crash. I know another bug similar to this has
been reported, however it was in reference to a specific app and cited the app
and global menu failing, whereas in this case the app continues to work
perfectly, but it is the whole of KDE Plasma that crashes.
- Unusual behaviour I noticed:
The unusual behaviour is noted above.
- Custom settings of the application:
There are no custom settings that I know of being implemented. The reason I was
attempting to access the global menu was to change the settings.
The crash can be reproduced every time.
