I saw something like that when I was first using mutt-kz as well...
it ended up that I had compiled libxapian with one version of gcc (3.4.3
maybe?) and notmuch with 4.5.2, and the C++ runtime libraries were
incompatible between the two versions.  In my case, any time it tried to
throw an exception (e.g. when I removed a tag that was not present) it
would die with a similar stack trace.  (And, of course, that was on
Solaris :) )
