Developers of Sympa

[Olivier Salaun - CRU <address@concealed>]

Since version 3.3.6b.3 Sympa uses a new user_data_source 'include2' that 
provides cache in DB and mixed included+subscribed members. This new 
'include2' mode implies database structure changes, actually 3 new 
fields added to subscriber_table.

When using MySQL, Sympa tries to perform database structure changes 
automatically. 1 of the 3 new fields had been forgotten in List.pm and 
database update was not complete. This can lead to strange behavior of 
the 'include2' feature.

It you upgraded to a 3.3.6b.3/3.4.x release and didn't update the 
database structure yourself, then you should apply the following patch 
to sources, make install and restart sympa.pl :

Many thanks to Robert Marchand from Montreal University who reported 
this problem.
