After installation of Source-Tree it runs once. Then after exit and a fresh start it appears but at the same time immediately crashes with:

Other tools and git command line are working on the same system. An old version (before 1.9) worked too. I cannot use SourceTree anymore and had to switch to some other Git-UI.
