Description Gobinda Goshwami 2021-01-25 16:23:51 UTC

Application: partitionmanager (4.2.0)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.9-201.fc33.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 33 (Thirty Three)

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

This is exactly the steps I did,

1. Right click on selected (1.72TiB NTFS) unmounted partition, and select "Edit Mount Point" option from context menu.
2. Click "Remove" on "Edit Mount Point" dialog
3. Click "Save changes" on confirmation dialog
4. Crash

Hope this helps.

The crash can be reproduced every time.

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

Comment 2 Thibault Molleman 2021-02-20 18:45:53 UTC

My bug report was indeed a duplicate of this one, matches very well
Can't manage to get a backtrace though even after rebuilding the package with the debug option on.

partitionmanager (22.08.3) using Qt 5.15.7

Clicking "Remove" and saving when editing the mount point of a partition on an external hard drive would always crash the program.

It's 2TB and formated as btrfs if that makes a difference.

partitionmanager  version 23.08.3 
KDE frameworks 5.112.0
Qt 5.15.11

Clicking "Remove" and saving when editing the mount point of a partition of internal solid state disk always crash the program.

3 years old bug still valid.
