Bug 395190

Application: baloo_file (5.26.0)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.104-18.44-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
Playing music on Amarok and connected to a remote desktop session using xfreerdp in a multi monitor mode.

- Unusual behavior I noticed:

Music continued playing, but I couldn't interact with the desktop.  All my applications froze.

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