Upgrading from testing today (2006-03-20) breaks at least Tomboy (community) and xfce terminal.

Issuing this commands fix the xfce Terminal issues:
cd /usr/lib
ln -s libdbus-glib-1.so.2.0.0 libdbus-glib-1.so.1
ln -s libdbus-1.so.2.0.0 libdbus-1.so.1

I'll try to investigate how to fix tomboy, though the bug looks related. Probably compiling tomboy against dbus .net bindings 0.61-1 (if possible) will fix it.

Output when running Tomboy:
