Bug 373179

Application: baloo_file (5.21.0)

Qt Version: 5.5.1
Operating System: Linux 4.1.34-33-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
Steps to reproduce:
1. Switch to desktop 2
2. Launch any Java based GUI application (TWS, JabRef)
3. File baloo crashes

As far as I can tell, the application and the destop seem to work normally after that so maybe there is nothing here...

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
