Tim,
I made a new rebuild yesterday night (everything except the applications folder) and update the system this morning. I 
encountered dependency conflicts in tdepim. For example:
libkcal2b-trinity conflicts with libtdepim1-trinity-dev
I can resolve those by removing 3 packages:
- kipi-plugins-trinity
- libkcal2-trinity-dev
- libkcal2b-trinity

Until 6 days ago (my previous build) no conflicts whatsoever.
Just thought I would let you know. Is it something to be expect due to some recent changes made in between RC1 and RC2?

Cheers
   Michele
