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

I was in horrizontal symmetry mode and i selected a portion of drawing and scalled it vertically. Then when I hit enter I got a crash.
I have got 2-3 crash in recent days from krita built from master, which occured while applying transform

The crash can be reproduced sometimes.

-- Backtrace:
Application: Krita (krita), signal: Aborted
