Example of bad line break in subject header was Re: [Mailman-Users] Upgrade from 2.0.x to 2.1.1-- incorrect padding error.

I'm enclosing below the full headers from Sumeet P's recent message, as 
they reached me.  This shows the formatting problem discussed last week, 
mentioned on the Mailman-Users list by Sarah from NOW and seconded by me, 
and also turned over a little on the Developers list.

The discussion on Developers included requests for an example that would 
reproduce the problem.  I don't know if this one will show the same 
behavior if re-tried on another installation, but here we can at least see 
it happening someplace we can observe in common.  (In case this gets 
mangled on the way back through, the Subject header as I've received it and 
pasted below is: first line " [Mailman-Users] " then second line a Tab and 
the rest "  Upgrade from 2.0.x to 2.1.1-- incorrect padding error. ")

I've installed the recommended Headers.py patch (and checked that it is 
/this/ headers.py that is being used), and I thought briefly that the 
problem was solved for my installation -- but it isn't. I'll quote a 
subject string that I've seen problems with, but note that whether it's 
reproducible seems to depend on what list it's going through.  Here's the 
example: "[CUIP Activity]  NSPTECH 2097 Alex Wilson  Wednesday 2003-01-15 
OS install/Printer Install".  It breaks after the list tag [CUIP Activity], 
and so do test messages with longish subjects that go through that 
list.  But if I send a message with that same header through a Test list 
(or any of several others), it doesn't break funny.  I'm trying to figure 
out the differences between the lists, but haven't managed to make the 
error happen in the Test list by fiddling with Language Options and 

I'm close to ready to just suppress all wrapping in Subjects if that would 
cure this oddity.  Would that be a disaster waiting to happen?  How hard 
would it be (I don't know much about the Mailman python code)?

P.S.  The point was made in the Developers discussion that Eudora's 
handling of the newlines in the summary windows may not accord to the 
relevant standard.  Would someone who can speak to this fairly 
authoritatively feel like sending a report/suggestion in Qualcomm's 
direction?  This is indeed only bothering Eudora users here.  (Including me...)
