Double mode crashes emacs in message mode

[Niels Olof Bouvin]

Symptoms:

I usually use double-mode to enter Danish letters ('æøåÆØÅ'), when using
Emacs.  Double-mode requires you to hit e.g. ':' twice to produce an ':'
rather than a 'Æ', and this has worked without any problems in years.
However, in the past week (I cvs update my Emacs pretty regularly, and I
believe I first saw this behaviour Monday), hitting ':' (or ;[{'") twice
when in a Message buffer in Gnus (also cvs current) will cause Emacs to
crash.  If I do the same in another buffer, e.g. *scratch* it performs
flawlessly.
