Thanks.  I have checked in a fix which (hopefully) will guard against
this crash in the future.  

BTW, the crash had nothing to do with Gnus -- it was a crash in the
internals of redisplay for an empty buffer.

Two comments:

- Your emacs is "very" old -- please upgrade to an up-to-date CVS
snapshot, as we continue to fix bugs, and prefer to get feedback based
on the current CVS sources (trying to determine whether a reported bug
has already been fixed takes time).

- Luckily, this crash happened in a very small function, so I could
find the bug quite easily.  However, the information you provided
about the crash would usually be pretty useless, as it doesn't
pinpoint where the problem happened (some functions in emacs are very
big, so only getting the name of the function is typically not of any
use to us.  So please run CVS emacs inside gdb (if at all possible).
