Matthias suggested this:

    strace -o tr -tt  mutt ....

If you want less log to deal with you can strace a process from outside:

    strace -o tr -tt -p pid-of-mutt

That would let you fire it up just before the action (change mailbox) 
which you know contains the delay. Might get you a better targeted log.
