Bug 373634

Application: dolphin (16.08.3)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.13-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

Occasionally, during startup and session restore, dolphin crashes. Since most of my dolphin instances use the split view, it may be related.

The crash can be reproduced sometimes.

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