Bug 365296

Application: baloo_file (5.6.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-64-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
insert usb flash
run kde partition manager
remove partition from flash, create the new one with NTFS and click Apply
that's all, app was crashed

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File (baloo_file), signal: Aborted
