It should be said that the current solution of looking into the database 
and trying to deduce what Evolution sees is a really bad idea. This is a 
temporary solution and we are asking for pain if we stick with it. 
Evolution can do whatever they want here with the database schema (i.e. 
change it).

Are you able to debug this at all and give us any indication of where 
the problem is?

There might be some issues here. We haven't received many/any? reports 
of anything like this yet. Maybe it hasn't been used by many people yet. 
I certainly haven't had any issues with it yet but I am not a heavy user.

We have another solution in TRUNK too, which allows evolution to push 
the data to Tracker instead of Tracker dipping in and pull data from 
Evolution's database. This was done by Philip. Unfortunately the change 
requires a newer version of Evolution and to be configured to enable in 
Tracker (since Evolution hasn't been released yet? with these changes).

As soon as possible, we will use this method since it is much more 
reliable than the current solution.
