            Bug ID: 432704
           Summary: Hang everytime at KDE Partition Manager startup after
                    setting Active Backend to KDE Partition Manager Dummy
                    Backend
           Product: partitionmanager
           Version: 4.2.0
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: andr...@stikonas.eu
          Reporter: njjust...@gmail.com
  Target Milestone: ---

Application: partitionmanager (4.2.0)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.13-200.fc33.x86_64 x86_64
Windowing system: X11

-- Information about the crash:
- What I was doing when the application crashed:

Launched KDE Partition Manager. The program loads with all blanks windows for
each GUI pane and then proceeds to rapidly flicker a blue rectangle around the
"Please select a device" window while displaying a spinning loading cursor
indefinitely. Clicking on menu items does nothing and only clicking the X works
to close the program with a crash.

- Custom settings of the application:

Before when KDE Partition Manager would load successfully I had not yet set
Active Backend to KDE Partition Manager Dummy Backend.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Partition Manager (partitionmanager), signal: Aborted
