I had him narrow down the bad emails by divide and conquer out of his 85,000
mails in that folder :) He gave me two examples, I looked at them and 
they have
a bunch of nulls right in the middle of the email, with more email text 
at the end.
Some kind of corruption.  He could cause the assertion by doing a body 
search.
I was able to reproduce this myself with the attached tar of the test 
maildir. Thanks.
