Detaching from program: /usr/bin/plasmashell, process 6148

Reproducible: Always

Steps to Reproduce:
1. Remove the package that provides baloofile
2. Disable indexing
3. Try and search for some application

Actual Results:  
Plasma crashes

Expected Results:  
Plasma does not crash
Comment 1 Rohan Garg 2015-09-08 21:45:54 UTC 
Ah right, you should probably also make sure that you don't have a db cache of any sorts with baloo, so the best way to test it would be with a new user probably.
Comment 2 Rohan Garg 2015-09-16 00:41:06 UTC 
Git commit 3312d6f3f4b80ec04e86c2ea103adc51ade0f020 by Rohan Garg.
Committed on 15/09/2015 at 23:20.
Pushed by garg into branch 'master'.

Add error checking in various bits so that Baloo doesn't crash when disabled.
