Hi.


Recently XEmacs 21.4p16 entered Debian unstable. I think that my problem
started with that, but I don't know - here we go:

When I enter my spam-group, XEmacs starts using a lot of CPU, but
nothing seems to happen. I let it sit for 5 minutes, without it
(seemingly) getting anywhere.

Here's the backtrace I get, if I kill xemacs after starting it from
the commandline, try to enter the spam-group, and then wait for 5
minutes:

 asjo@topper:~$ xemacs

 Lisp backtrace follows:

Attached is the email it seems to be chewing on for reference.


Here's the start of two other traces (same symptoms):

 Lisp backtrace follows:

   string-match("=\\?\\([^][- ()<>@,;:*\\\"/?.=]+\\)\\(?:\\*[^?]+\\)?\\?\\(B\\|Q\
 \)\\?\\([!->@-~ ]*\\)\\?=" "=?utf-8?q? cell quantity and ?=")
   # bind (word)
   rfc2047-parse-and-decode("=?utf-8?q? cell quantity and ?=")
   # (unwind-protect ...)


 Lisp backtrace follows:

   string-match("=\\?\\([^][- ()<>@,;:*\\\"/?.=]+\\)\\(?:\\*[^?]+\\)?\\?\\(B\\|Q\
 \)\\?\\([!->@-~ ]*\\)\\?=" "=?utf-8?q?Theodora Cay?=")
   # bind (word)
   rfc2047-parse-and-decode("=?utf-8?q?Theodora Cay?=")
   # (unwind-protect ...)


Any ideas?


 XEmacs 21.4 (patch 16) "Corporate Culture" [Lucid]
 (i386-debian-linux, Mule) of Sun Dec 12 2004 on penell

 No Gnus v0.3 (cvs from 2004-11-22, I re-bytecompiled after installing
               the new XEmacs packages).


 The box is a P4 2.4 GHz with RAM enough, so I don't think it is
 because I'm being too impatient.


  Best regards,
