cyrus21, version 2.1.17-3. It's on the vanrees.org server to which I
have root access together with my brother. I can also run mutt on that
machine. It has the same muttrc as I have at home, courtesy of
subversion.
I have offlineimap in a cronjob since a few days. The crashes started
long before that.

Lots of question marks in the backtrace indeed.

Okay, I did all that, produced a new core dump and here's the gdb
output.

Previous frame inner to this frame (corrupt stack?)
(gdb)
Doesn't seem too useful to me at first sight, with all those question
marks and the possible corrupt stack.

I'll try that and let you know.
I'll keep mutt open on the server as well (logged in via ssh) and see
if mutt crashes there too. No /usr/lib/debug or valgrind there BTW; I
like to keep it clean. Server is also Debian Sarge. Mutt is the same
version on both machines: 1.5.6-20040907+2.
