Crash due to Japanese file name in "File Status" list

If I add some file name with japanese character to git working directory, and open source tree which already has that git repository, then sourcetree crashes right after opening. I suspect that this is due to Japanese file name, because when I change the file name to english characters, the crash did not occur.
