[Mailman-Users] Upgrade from 2.0 to 2.1.5 breaks on pending_subscriptions.db

[Fergus Donohue]

Has anyone else come across this and if so what's the solution?

I'm running an upgrade of our mailman install in a test environment and it's breaking with the following error. I'm running on Solaris 8 with Python 2.3.4. The 2.0 version of Mailman was using python 1.6.

phoenix on old-hawk {731}# ls -la /home/misc/mailman/data/pending_subscriptio>
-rw-rw-r--   1 mailman  mailman       97 Aug 16 14:27 /home/misc/mailman/data/pending_subscriptions.db
phoenix on old-hawk {732}# tail -10 fd.ins.3
Updating Mailman 2.0 pending_subscriptions.db database
Traceback (most recent call last):
  File "bin/update", line 780, in ?
    errors = main()
  File "bin/update", line 704, in main
    update_pending()
  File "bin/update", line 583, in update_pending
    addr = data[0].address
AttributeError: 'str' object has no attribute 'address'
make: *** [update] Error 1

If I dump pending_subscriptions on a box that can dump .db files I get:

phoenix {353}# ./dumpdb /tmp/pending_subscriptions.db
{   448473: ('emanuel.soreteanonescu2 at mail.dcu.ie', 'cycbtsvf', 0, 1089674437),
    'lastculltime': 1089723840}
phoenix {354}#

Does anyone have any ideas what's going on? 
Thanks,

Fergus.
