[lug] mailman bug stalls delivery queue - post includes problem resolution

[Ferdinand Schmid]

HI,

My mailman installation (mailman-2.0.14-18) stopped delivering messages.  The error log 
got huge with errors of the type:

Oct 01 16:25:01 2004 qrunner(15575):      splitsubj = string.split(subject)
Oct 01 16:25:01 2004 qrunner(15575):   File "/usr/lib/python2.2/string.py", line 117, in split
Oct 01 16:25:01 2004 qrunner(15575):      return s.split(sep, maxsplit)
Oct 01 16:25:01 2004 qrunner(15575): AttributeError :  'NoneType' object has no attribute 
'split'

MailCommands

Fortunately somebody had run into the same problem recently and posted a fix here:

http://www.mail-archive.com/mailman-users%40python.org/msg27378.html

They basically suggest the amazingly simple fix:

/usr/lib/mailman/Mailman/MailCommandHandler.py file, line 163, as follows:

        if (subject == None): subject = ''
        splitsubj = string.split(subject)

Since many folks on this list may be running mailman I hope this post helps somebody.
