Sentry Crash Report:

Description Raghavendra kamath 2016-04-07 14:02:55 UTC

Application: krita ()
 (Compiled from sources)
Qt Version: 5.6.0
Frameworks Version: 5.20.0
Operating System: Linux 4.4.5-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

There are actually two things in this bug 
1) backup kra file is not recognised in krita
2) pressing ok in unknown file type dialog box crashes krita

I tired to open a backup file in krita ( the one with .kra~ extension) Krita complained about it being unknown file type, so then i pressed the "OK" button in warning dialog , immediately krita crashed I tried it two or three more times it happened everytime.

I tired with some random files which are unknown or not supposed to open in krita, each time I press ok it crashes krita

The crash can be reproduced every time.

-- Backtrace:
Application: krita (krita), signal: Segmentation fault

Comment 1 Halla Rempt 2016-04-08 06:19:44 UTC

The crash itself got fixed yesterday, accidentally, but Krita still should be able to recognize the filetype.
