I can't reproduce this with that regex, but after some experimenting,
I've seen it elsewhere with otherwise legitimate regexes.  The way to
fix it is to just remove that statusbar message (since, with
illegitimate regexes, it'll be displayed constantly and overwrite any
other statusbar messages, which is another problem).  However, that's a
translation change, so it'll have to wait a bit until after 1.3.12 is
out.
