We're also doing something like this with a Perl script written by a colleague
based on groupOfNames/member schema and OpenLDAP's slapo-memberof.

I'd be interested to see this. Will you release it as open source?
Also it might be worth to think about turning it into a syncrepl client if the
LDAP server is an OpenLDAP server. This way changes to groups would be
immediately synced to Mailman.

Yes, that's expected. Frankly the exceptions generated by the C wrapper module
_ldap.so are not very elegant and sometimes inconsequent. If you just want to
write a log message the exception the most simplest thing is to call
str(error). This will always work and practical experience shows the
information provided is enough to find most error causes.
BTW: Cleaning up exception handling is on my to do list. Everyone having some
spare time left is welcome to jump on in.
