Crash on canceled update (or commit)

On 0.8.2:
1) After being asked to update, i confirmed
2) No progress on the bar was visible so i pressed "cancel"
3) After adding some files to the git index, i pressed the "commit" button on the toolbar
4) Shortly after starting to write the commit message Sourcetree crashed

After restarting SourceTree it's at version 0.8.3
