Well, after a little more investigating, I think I have solved the problem.  
It turns out that the login was failing due to one of the new mail 
messages in the user's inbox.  Renaming the file to a .TXT file, and the 
login works.  Examining the message more closely, it appears to be 
from a list, and there is nothing to the left of the @ sign in the email 
address specified in the "To:" field in the headers.  Would this be a 
good enough reason to cause Apache/PHP to segfault?
