Planner Backport Update causes conflicts

[Andy]

Attempting to upgrade Planner from 0.13-0.4~5.04ubp1 to 0.13.0.4~hoary1
causes the message "Depends: libgda2-3 but is not going to be installed"
Same message for upgrading libgda2-common from 1.1.99-1 to
1.2.1-2ubuntu2~hoary1.

If I try to install libgda2-3 I get:
	To be Removed
		glade-gnome-2
		gnome-devel
		libgda2-1
		libgnomedb2-3
		libgnomedb2-common
	To upgraded
		libgda2-common
		planner

Either I'm missing something or there are dependancy problems with
libgda2-3.
