Bug 360089

Application: dolphin (15.12.2)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
Upon dolphin startup, it directly crashes. 

Additional information : Seeing that the crash goes into Baloo, I feel it might be related to the disk failure I experienced lately. Data was recovered, but to be honest, I can't guarantee integrity. I believe it shouldn't crash though  :)

The crash can be reproduced every time.

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