Check and Select 3 "pending" (changed / uncommitted files), right-click and select "Commit... Shift-Alt-C" ... source tree crashes!

I just updated to the newest source-tree.
many pending changes and 3 new files, also 12 commits behind.

This happens EVERY TIME!
It does NOT matter if you ONLY check them, or ONLY select them or use the context menu or the keyboard short-cut, nor which or how many you select ... doing a COMMIT always fails!
