Most likely your problem is that the delegate has already been 
deallocated when this method get called. A simple way to test this is to 
retain the delegate in the setDelegate: method. Of course this will leak 
an object and should only be done to test if this is actually the issue.
When you are sure about it, things get complicated :-(
You will have to find out where the delegate get set and what should 
keep him alive outside of the CWService and of course, why this 
mechanism isn't working.
I don't understand much of Pantomime or GNUMail, but from a short look I 
think that CWService is a sort of super class of the different 
connections and TaskManager seems to be the delegate used. You will have 
to watch, when TaskManager gets deallocated.

Hope this helps
