Thank you, Paul, you hit the nail on the head with your first educated guess.  
The problem is present with 9624f609493da7c08016ba00d6895bad0fe26a0e, and the 
problem disappears when reverting to the previous commit 
cb367c8e0d4a881acf8255e1ff6bdd6442efb538.  You saved me a lot of time -- 
greatly appreciated!!!

I will reset to *26a0e and revert each component of that commit one by one in 
an effort to isolate the problem.  When I have an update on my progress, I'll 
post another comment to the mailing list -- it may require a good night's sleep
