MULE crash

[Michael Sperber]

Brain-dumping a problem I've been seeing for a while:

Opening certain messages with funky encodings with Gnus crashes my MULE
XEmacs for me with an assertion failure.  Happens only when I use the
nnimap backend.  I've attached one.

Aidan, you seem to be the go-to guy for this kind of thing.  Is this
enough for a filed bug report?

Fatal error: assertion failed, file /afs/informatik.uni-tuebingen.de/home/sperber/build/xemacs/src/text.h, line 589, ibyte_first_byte_p_1 (* (ptr), "/afs/informatik.uni-tuebingen.de/home/sperber/build/xemacs/src/text.h", 589)
