Application: krita (2.9.9 Animation Edition (beta) (git c5001ab))
KDE Platform Version: 4.14.14
Qt Version: 4.8.7
Operating System: Linux 4.2.5-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was Undo-ing a few steps using the undo hsitory docker, back to the opened state. Steps were duplicating and merging layers, then converting color space from 8 bit sRGB to 16 bit sRGB.

- Unusual behavior I noticed:
Maybe unrelated but when converting color space, my transparent players become much lighter and partly destaurated. I was trying to find out more about this phenomena, or find a workaround, when the crash happened.

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