Hi Aaron,

That's a pity. I am using Julien Danjou's emacs-snapshot package for
debian and actually I only noticed the infinite loop on this thread
after restarting emacs some unknown time after the package was
upgraded. The package was upgraded from 20120105 to 20120111.

I haven't been using this snapshot of emacs for very long, so possibly
the problem might occur with other threads. To test this thread, I
copied it out of my maildirs with mutt, deleted the original messages,
ran "notmuch new", copied the mbox thread back into my maildirs, then
ran "notmuch new" again, and the problem was still there.

I copied 4 backtraces which appear below. I pressed the 'a' key when
viewing the thread, then C-g.

They were run with notmuch git commit efa5d6cb32. Since then I went back
to 0.11 because it seems like the reply function stopped working.


Cheers,
