            Bug ID: 412503
           Summary: Virtual Desktops: Index error suspected
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: dpalmigiano at gmail.com
  Target Milestone: ---

Application: kcmshell5 (5.16.5)
 (Compiled from sources)
Qt Version: 5.13.1
Frameworks Version: 5.62.0
Operating System: Linux 5.3.1-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: Trying to rename virtual
desktops, but every time I tried, the first one's name would change and if I
tried to apply any change at all the crash occured. Every time.

- Unusual behavior I noticed: I am also unable to get window thumbnails for alt
+tab. I suspect it might be related.

- Custom settings of the application: Nothing unusual.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
