It's been already discussed here and it : http://does-not-exist.org/mail-archives/mutt-dev/thrd88.html I've been using Mutt from gdb and trying to get some extra information that I'm attaching below, just in case someone can bring some light to this issue. If further information is need, I'm willing to provide it. It seems that the SEGV occurs when a thread is being sorted and a new message related to that thread is been added while syncing to the IMAP server (WU-IMAP, in my case).
