I just got an error report for nXhtml where the error in the subject
line happens. This is in a buffer with multiple major modes (using
mumamo.el) so it is not an Emacs bug. I just do not understand what
the error mean. Can someone please shed some light upon it?

It means that a font-lock pattern referenced a subexp of a regexp that
does not exist or did not match, i.e. (match-beginning 3) returned nil.

Exactly. And the (7) indicates it's probably one of the rules in
font-lock-syntactic-keywords rather than in font-lock-keywords. i.e. it
either means one of the rules in font-lock-syntactic-keywords is using
the wrong group number, or it needs to be tweaked to set the
LAXMATCH option.

Thanks, that cleared my thoughts enough. The problem was that I had
forgot to add save-match-data when I rearranged some code in
mumamo.el. (Calls to chunk dividing routines is done from the
font-lock machinery.)
