Bug 380423

Application: partitionmanager (3.0.1)

Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.11.3-300.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

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

startet Partition Manager from Application launcher, was asked for root's password, entered it, but Partition Manager still wanted to start without root priviledges (dialog prompted). Accepting that, it crashes, every time.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Partition Manager (partitionmanager), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
