Description Raghavendra kamath 2015-07-16 09:02:04 UTC 
Application: krita (2.9.6 (git 5090c13))
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

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

I am using Krita from git.

I was using the Line tool to draw something,
Suddenly there was a popup with some text ( I may sound dumb but sorry i didn't read it properly ), But it gave two options abort and ignore.
When i pressed abort it crashed krita and Dr. konqui came up.

This has randomly happened earlier too.

The crash can be reproduced sometimes.

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