When I start SourceTree 2.0.4, it gives a crash message. The application keeps running though, but the message appears again and again when I try to open the Preferences or click buttons.

Removing the ~/Library/Application Support/SourceTree folder didn't help.

SourceTree 2.0.3 is working fine.

This is the crash log:
