[Mailman-Users] Mailman problem on Debian

[Erick Mechler]

:: TypeError: _ascii_lower() takes exactly 1 argument (0 given)
:: Site list for mailman (usually named mailman) missing
:: Please create it; until then, mailman will refuse to start
:: 
:: --end errors
:: 
:: This occurred after an update on Debian unstable.  There *IS* a sitewide
:: list named mailman, so I don't know why it says that it is missing.  This is
:: Mailman 2.1.3.  Any ideas?

What is the value of MAILMAN_SITE_LIST in Defaults.py and mm_cfg.py?  Does 
it match the name of your MM Site List?
