Bug ID: 470946
Summary: Unmounting the drive in plasma before clicking Apply
causes SEGFAULT
Classification: Applications
Product: partitionmanager
Version: 23.04.1
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: andr...@stikonas.eu
Reporter: ondrej.m...@seznam.cz
Target Milestone: ---
Application: partitionmanager (23.04.1)
Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 6.2.15-300.fc38.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora release 38 (Thirty Eight)"
DrKonqi: 5.27.5 [KCrashBackend]
-- Information about the crash:
Unmounting partition in the partition manager does not actually unmount the
partition. I'm not sure whether that's intended behavior.
Partition manager does not check, whether the drive is still mounted before
applying the changes, which can result in segfault.
Reproducer:
1. Connect a flash drive to the computer
2. Right click the flash drive partition in partition manager and unmount it
3. Create a new partition on the flash drive
4. Unmount the flash drive in plasma applet
5. Click apply in partition manager
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: KDE Partition Manager (partitionmanager), signal: Segmentation
fault
