Bug 422851

Application: partitionmanager (3.3.1)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.3.0-59-generic x86_64
Distribution: Ubuntu 18.04.4 LTS

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

The application was stuck while formatting a USB drive. I removed the drive to see if that would unfreeze it but it crashed instead.

- Unusual behavior I noticed:

The application appeared frozen. I tried cancelling the operation but there was not change in behavior. Trying to close the window only said that the application was not responding and whether to force stop it.

- Custom settings of the application:

None.

The crash can be reproduced every time.

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