I got a report for that mutt hangs when fetching headers:
https://bugzilla.redhat.com/show_bug.cgi?id=516210
It seems to be caused by server returning for some messages this:
{{{
[2009-08-15 11:02:13] 4< * OK Message 1992 no longer exists
[2009-08-15 11:02:13] 4< * 1992 FETCH (FLAGS (\Seen Old) UID 4076
INTERNALDATE "24-Sep-2008 10:57:10 +0200" RFC822.SIZE 5862
BODY[HEADER.FIELDS (DATE FROM SUBJECT TO CC MESSAGE-ID REFERENCES CONTENT-
TYPE CONTENT-DESCRIPTION IN-REPLY-TO REPLY-TO LINES LIST-POST X-LABEL)]
"")
}}}
mutt prints to debug "msg_fetch_header: ignoring fetch response with no
body" and it will hang in imap_read_headers() as msgno won't reach msgend
to end the for cycle.
Making the cycle break after the last OK is received makes mutt segfault,
there are holes in ctx->hdrs.
