Luke:/var/lib/mailman/lists/mailman# cmp config.pck config-orig.pck
config.pck config-orig.pck differ: char 46, line 2

Line 2 in the dumpdb output does not have 46 characters, so I assume this 
refers to the raw file??

Now look at this:

Luke:/var/lib/mailman/lists/mailman# cmp config-orig.pck 
config-orig.pck config.pck.last.orig differ: char 46, line 2

So the first and third cmp results above are consistent and show the same 

*****  And if you're not already going crazy, this will do it:

Earlier I sent you this diff result:

Luke:/var/lib/mailman/lists/mailman# diff config.pck config-orig.pck

But now when I run it, I get:

Luke:/var/lib/mailman/lists/mailman# diff config.pck config-orig.pck
Binary files config.pck and config-orig.pck differ

So I think we've finally beaten the horse to death and I can barely keep it 
straight anymore!  These are all cut and paste results, so it's not just my 

I don't under stand why they diff'ed the same this morning and not now!

Anyway, we know something was wrong with config.pck and using the 
config.pck.last file fixed it.
