[Mailman-Users] 2.0.13 qrunner crash on message with no Subject header

[Myk Melez]

qrunner on my mailman 2.0.13 installation crashes with the following 
error when it encounters a message with no Subject header:

It looks like the problem is in MailCommandHandler.py, which tries to 
split the header without making sure it exists first.  The attached 
patch seems to fix the problem.  Is the developers list more appropriate 
for this message?  Is the project even accepting patches for 2.0.13 
anymore?  I can't find the equivalent code in the latest version from 
CVS, so perhaps this is a 2.0.13-only problem (or else I don't know 
where to look).
