Bug Description

Jonathan Pobst's Pinta 1.6-prerelease for Windows from: https://dl.dropboxusercontent.com/u/1481774/pinta-dev-1.6.0.0.exe

Windows 7:

This looks like regression too:
a) Open Pinta
b) Line/Curve and draw some line
c) Rectangle Select and mark some area on canvas, but do nothing else (do not crop selection or do no deselect)
d) Undo once. Ok.
e) Undo again crash:
