The plot thickens. With this patch applied, I can generate an emacs
segfault with

1) EMACS=emacs23 ./devel/try-emacs-mua -q

2) M-x notmuch-search <return>

3) tag:inbox <return>

without the patch, I get a search view, and the message

        Wrong type argument: number-or-marker-p, entry-main

I'm not able to trigger a lisp backtrace.
