Indeed: http://www.boost.org/libs/filesystem/doc/operations.htm#empty_rationale I think we shouldn't just assert in this case. It took me some time to find out the reason why I couldn't save anymore without crashing LyX. We should check if the directory exists, we should check and tell the user: "the backup directory $DIR does not exists. Should I create it?" Jürgen
