Unable to process subscription requests

[SEWilco]

After approving subscription requests for list 'mailman', administrator was told a bug was encountered.

admin(23231): [----- Mailman Version: 2.1.12rc1 -----]
admin(23231): [----- Traceback ------]
admin(23231): Traceback (most recent call last):

[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)]

The merge of line 773 from 2.1 to 2.2 rev 1027 implies it is recent code in 2.1.

Thanks for the report. You are correct that this was introduced by a recent change in 2.1.12rc1 and it is now fixed for the next release.
