[turba] Distribution list inconsistencies

[Josef Spillner]

Hello,

deleting a contact which is referenced by a distribution list does not take 
the reference off that list.

Since no reverse dependencies are stored in the database, I assume the only 
way to fix that would be to traverse all lists and erase any occurences via 
Turba_Group::removeMember().

So is it implemented this way for performance reasons (the method 
listMembers() seems to suggest that)?

I'm currently developing a Horde newsletter module based on Turba, and thus 
would be glad to know some details :)
