Bug ID: 393275
Summary: Crash after dismissing "Scanning devices..." and
closing KPM
Product: partitionmanager
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: andr...@stikonas.eu
Reporter: waz...@protonmail.com
Target Milestone: ---
Application: partitionmanager (3.2.1)
Qt Version: 5.9.4
Frameworks Version: 5.44.0
Operating System: Linux 4.15.17-300.fc27.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
Steps to reproduce:
1. Run KPM
2. Enter root password
3. Close "Scanning devices..." with 'X'
4. Immediately close KPM while the cursor is still busy
5. KPM crashes
Additional info:
This also occurs after an operation was completed. After the report dialogue
window is dismissed, the user may want to quit immediately and does above steps
3 and 4. It doesn't seem to happen after the spinner cursor is gone or when run
without root privileges.
The crash can be reproduced every time.
-- Backtrace:
Application: KDE Partition Manager (partitionmanager), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
