Bug 382296

Application: kdeinit5 (17.04.1)

Qt Version: 5.7.1
Frameworks Version: 5.35.0
Operating System: Linux 4.11.9-300.fc26.x86_64 x86_64
Distribution: "Fedora release 26 (Twenty Six)"

-- Information about the crash:
- What I was doing when the application crashed:
Logging into my KDE/Plasma session. Dolphin immediately gave a segfault. Restarting it from within the session works.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
