Mail 2.1.12: We're sorry, we hit a bug!
Hi Environment: Mailman 2.1.12 on Amazon Linux 2012 with Python 2.6.9 and Virtualmin 4.0.5 GPL All our lists are under Emergency moderation. When a moderator goes to process held-messages and select "Preserve messages for the site administrator", then we see the following error: Bug in Mailman version 2.1.12 We're sorry, we hit a bug! Please inform the webmaster for this site of this problem. Printing of traceback and other system information has been explicitly inhibited, but the webmaster can find this information in the Mailman error logs. And then we see the following in /var/log/mailman/error file: Feb 18 21:42:26 2014 admin(10273): @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ admin(10273): [----- Mailman Version: 2.1.12 -----] admin(10273): [----- Traceback ------] admin(10273): Traceback (most recent call last): admin(10273): File "/usr/lib/mailman/scripts/driver", line 112, in run_main admin(10273): main() admin(10273): File "/usr/lib/mailman/Mailman/Cgi/admindb.py", line 165, in main admin(10273): process_form(mlist, doc, cgidata) admin(10273): File "/usr/lib/mailman/Mailman/Cgi/admindb.py", line 716, in process_form admin(10273): forward, forwardaddr) admin(10273): File "/usr/lib/mailman/Mailman/ListAdmin.py", line 167, in HandleRequest admin(10273): forward, addr) admin(10273): File "/usr/lib/mailman/Mailman/ListAdmin.py", line 244, in __handlepost admin(10273): msg = cPickle.load(fp) admin(10273): ValueError: could not convert string to float Not selecting the checkbox titled: Preserve messages for site-administrator, is processing the emails just fine and there are no issues.

It looks like this might be an actual bug. There is an incompatibility between Mailman 2.1.12 and Python 2.6.x in this area, but not right there. At lines 205 and 254 in your version of ListAdmin.py, g(msg, 1) needs to be changed to g.flatten(msg, 1). However, that doesn't cause what you're seeing. Do you have HOLD_MESSAGES_AS_PICKLES = No in mm_cfg.py. If so, I think there is a bug with this. Unfortunately, I'm traveling this week and it will take be a while to investigate/fix this. In the mean time, if that is the issue, you can remove that from mm_cfg.py if you don't need it for other reasons.

That is a mail-archive.com issue. You could search Google for
inurl:mailman-users site:mail.python.org "We're sorry, we hit a bug!"
but that returns over 5000 hits, most if not all of which are not
relevant. It's much better to search with something like
inurl:mailman-users site:mail.python.org "ValueError: could not convert
string to float"
which returns only 8 hits, including a couple from 2003 and 2004 which
indicate this is an old bug.

It turns out that for many years it has not been possible to preserve
messages for the site-administrator if HOLD_MESSAGES_AS_PICKLES = No.
This is now reported at
https://bugs.launchpad.net/mailman/+bug/1282365 and fixed at
http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/revision/1448.
