Reproducible: Always

Steps to Reproduce:
1. Login using KDE
2. Message window pops up saying that baloo file extractor has crashed.


Actual Results:  
Daemon crashes.

Expected Results:  
Daemon does not crash.

Stacktrace provided.

I'm unsure if the extractor program restarts, but I think it does and it continues to run.

I was not sure what version of baloo was running but here's the package installed under f23:
