Debian Squeeze: installing trinity requires to remove gnome package

Hi, I use Trinity on 3 machines (1×Lenny+2×Squeeze) and was surprized installing Trinity on Squeeze: aptitude asked me to remove the gnome package and a few others (sorry I didn't have a copy of the aptitude messages). The main reason was about desktop-base (initially 6.0.5) conflicting with desktop-base-trinity (5.0.3-5). I assume this isn't the expected behaviour since there's no reason to remove gnome when installing trinity. However, I don't miss gnome at all but still I am surprized. Does this mean that there will be more and more issues when installing trinity on systems with recent libraries in a near future? I wonder how much trinity will evolve in parallel of kde4/gnome packages and underlying libraries that also evolves...? Nicolas
