Sentry Crash Report:

Description Marty 2015-01-16 02:54:18 UTC

Application: krita (2.9 Beta 2)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Linux Mint 17 Qiana

I opened a new image using a predefined tempate (A3).  I scibbled on it.  Closed the app and selected no when asked to save.  App crashed.  I don't have  QT dbg loaded, can load and rerun if needed. 

The crash can be reproduced every time.

Reproducible: Always

Steps to Reproduce:
1. start krita
2. ctrl-n - create new document (I did this with the A3 template)
3. scribble on the canvas
4. close krita
5. select no when asked to save

Actual Results:  
Segfault

Expected Results:  
not seqfault

Comment 1 Marty 2015-01-16 03:03:56 UTC

i just came across 337005 which may be a dup, hard to tell as that one doesn't have a stack trace.

Comment 2 Halla Rempt 2015-01-29 10:40:50 UTC

Hm, the crash happens in the reference images docker. There must be some image in the directory the reference images docker reads that crashes Qt :-(
