Hi,

A list user posts started being shunted with the following showing up in
the error log:

ValueError: unpack list of wrong size

I've search through the archives and found other posts regarding this
error but no resolution was found.  They were from some time ago so I'm
hoping someone may be able to provide some insight into this now.

We're running Mailman 2.1.5 on FreeBSD 4.6-STABLE with python2.3 and
postfix 1.1.11

Any assistance will be appreciated.

Thanks,
Sean
