Bug 351299

Application: baloo_file (5.6.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Running a script that uses parted, and manually mounting newly created partitions.
The new partitions are(in this case) the same as the old ones (I was rerunning the script to reimage the sd card)

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File (baloo_file), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
