It may appear on opening or saving of some file if its path contains some non-ascii characters. Also if started in such directory (without specified project file), then on attempt to open some file it tries to start browsing from current directory and showes, that can't find such directory (path, printed in error messages, has question marks inserted instead of non-ascii characters).
However... in open/save-file-dialog such problem doesn't appear: i can easily find and select file to save, but saving itself will fail.
