I can't reproduce a problem, but time to time this crash appears. Sorry for not having step-by-step instructions.
I am using Pinta-development currently for few months and this problem did not appear for few months. Maybe this problem does not appear any more in development.
If problem reappears and I have a step-by-step instruction, I will open new bug report. I am closing this bug as Invalid.
