Comment(by jaymzh):
So, my tcpdumps seem to support your theory that mutt sends a request...
however it seems like it's not finishing sending the request (perhaps due
to
stack corruption?). Here's the tcpdumps:
From my desktop:

The logs on the imap server show:
{{{
Aug 15 08:57:13 virt cyrus/imaps[17989]: Connection timed out, closing
connection
}}}
and the last thing before that is expunging messages at 08:30:10 - so it
never
seems a full request. Note that once again, the stack is corrupted:
{{{
#0 0xb7d70cdc in recv () from /lib/libc.so.6
#1 0xb7e4d91c in ?? () from /usr/lib/libgnutls.so.26
#2 0x00000004 in ?? ()
#3 0x093944c8 in ?? ()
#4 0x000004dc in ?? ()
#5 0x00000000 in ?? ()
}}}
But note that it's not missing symbols, as I can get a nice stacktrace
with a
happy mutt:
{{{
#0 0xb7d5f586 in poll () from /lib/libc.so.6
#1 0xb7fe19ca in _nc_timed_wait () from /lib/libncursesw.so.5
