Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:

drawing straight lines in canvas only mode. Crashed when i clicked save. 
When I open Krita again all dockers are gone and I must set them again

The crash can be reproduced sometimes.
