Problem entering some IMAP groups

Problem entering some IMAP groups

[Bruce Z. Lysik]

Hi folks,

I'm running XEmacs 21.1.10 at work with gnus right out of CVS.

When I try to enter some of my IMAP groups I get an error.  Here's the
result of debug-on-error set to t.  Any help would be appreciated.
Thanks.

Does the attached patch work?  Out of curiosity, when you get that
error, could you mail me the content of your " *nntp*" buffer?  I
think your NOV cache might be corrupted.
