Bug ID: 451572
Summary: Crash when closing main window while being prompted
for root password
Product: partitionmanager
Version: 21.12.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: andr...@stikonas.eu
Reporter: bugs.kde....@derflupp.e4ward.com
Target Milestone: ---
Application: partitionmanager (21.12.3)
Qt Version: 5.15.3
Frameworks Version: 5.91.0
Operating System: Linux 5.16.14-arch1-1 x86_64

-- Information about the crash:
When starting KDE Partition Manager as a regular user, it prompts for the root
passwort. While the prompt is shown, the main window is blocked by a modal
window with the title “Scanning devices …”. The modal window can be closed by
pressing escape. Afterwards also the main window can be closed. Then, when
closing the password prompt, another password prompt appears. After closing
this one, another one appears, and so on. After closing several password
prompts, KDE Partition Manager crashes.
Besides fixing the crash, I think KDE Partition Manager should not immediately
ask for the root password again if the user just refused to enter it. It should
be easily possible to leave the applicaion without providing the root password.
The crash can be reproduced every time.
