See the FAQ at <http://wiki.list.org/x/lYA9>.

There is an issue with the list's data_version attribute vs. 
Mailman.Version.DATA_FILE_VERSION. When the from_is_list and other new 
attributes were added, Mailman.Version.DATA_FILE_VERSION was incremented 
to make it greater than the list's data_version attribute which in turn 
will cause the lists to be updated the first time they are instantiated.

Perhaps you had some other patches that incremented 
Mailman.Version.DATA_FILE_VERSION, so that the list's data_version 
attribute was not < Mailman.Version.DATA_FILE_VERSION causing the update 
to be skipped.

The way to fix this is to set Mailman.Version.DATA_FILE_VERSION to a 
value greater than the data_version attribute of the lists.

First run this bash script

for l in `/path/to/mailman/bin/list_lists --bare`
   do /path/to/mailman/bin/dumpdb /path/to/mailman/lists/$l/config.pck \
     | grep data_version

This will print the data_version for each list. If N is the largest such 
value, edit Mailman/Version.py to change the line


to set a value > N. Then visit the listinfo overview page which should 
update all the lists.

Then so this doesn't happen again, set DATA_FILE_VERSION back to 104 in 
Mailman/Version.py and create a file containing the single line

mlist.data_version = 104

and run this bash script

cd /path/to/mailman/bin/
for l in `./list_lists --bare`
  do ./config_list -i /path/to/above/file $l

That should fix things.
