[notmuch] Segfault searching for tags

[Jeffrey Ollie]

Getting the following segfault with 306635c2 on Fedora 12.  Seems to
be happening with any 'tag:' search that returns results.  For
example, 'notmuch search tag:inbox' and 'notmuch search tag:unread'
segfault but 'notmuch search tag:nosuchtag', 'notmuch search
subject:logwatch' and 'notmuch search video' seem to work fine.

Core was generated by `/usr/bin/notmuch search --sort=oldest-first tag:inbox'.
Program terminated with signal 11, Segmentation fault.
