[Pkg-mailman-hackers] Bug#443069: mailman: senddigests cron job: "TypeError: iso-8859-1"

[Julian Mehnle]

Package: mailman
Version: 1:2.1.9-8
Severity: important
Followup-For: Bug #384016

It seems that #384016 is not resolved yet.  I recently upgraded mailman
from 1:2.1.8-4 to 1:2.1.9-8, and now I am getting the following error
message whenever the senddigests cron job runs (i.e. daily):

| Traceback (most recent call last):
|   File "/usr/lib/mailman/cron/senddigests", line 94, in ?
|     main()
|   File "/usr/lib/mailman/cron/senddigests", line 86, in main

|   File "/usr/lib/mailman/Mailman/Digester.py", line 60, in send_digest_now
|     ToDigest.send_digests(self, mboxfp)

|   File "email/Message.py", line 242, in set_charset
| TypeError: iso-8859-1

I followed the trail of #384016 and found that its supposed fix (the
mailman package shipping its own "email" Python package) does not seem
to be in effect on my system:

| io:/usr/lib/mailman/cron> python
| Python 2.4.4 (#2, Aug 16 2007, 02:03:40)
| [GCC 4.1.3 20070812 (prerelease) (Debian 4.1.2-15)] on linux2
| Type "help", "copyright", "credits" or "license" for more information.
| >>> import paths
| >>> import email
| >>> email.__version__
| '3.0.2'
| >>>

Using python2.3 to run senddigests works around the problem as expected:

| io:/usr/lib/mailman/cron> sudo -H -u list python2.3 /usr/lib/mailman/cron/senddigests
| io:/usr/lib/mailman/cron>

What's going on here?  Has the inclusion of mailman's own "email"
package been reverted?
