[Mailman-Users] unshunt does nothing

I believe this issue is related to my other trouble with utf-8.

Once I hand-edited /var/lib/mailman/Mailman/Archiver/pipermail.py, per the suggestion in that message. I restarted Mailman and ran the unshunt command again.

The shunted messages cleared out and no errors appeared. Though there was no positive affirmation the shunted messages were cleared either. Is the 'shunt' command meant to display anything?

==== Per Mark

No. All unshunt does is move the .pck files from the shunt queue to the
original queue from which they were shunted. It does this silently.
The requeued entry is then processed again by the respective qrunner,
and this process either succeeds or possibly throws the same exception
that caused the shunting in the first place, in which case the message
is shunted again.

This is because the message is restored to it's original queue and
processed and throws the same exception that occurred before and is
shunted again.

Are there new entries in Mailman's error log when you unshunt?

What changed? Was the Debian package updated?
