(kubuntu-devel@ CCed for digikam)

As you can see in the PPA mentioned above, I managed to get most of the packages
building. The following doesn't build yet:

 * digikam
Debian has a newer upstream version than us, but the current Ubuntu package
isn't based on Debian, so I haven't tried to merge the whole thing. Either
someone (from Kubuntu? :)) manages to merge the Debian changes (better), or we
just keep the current version and fix it.

 * gnome-mousetrap
According to Debian bug #655930, there are real incompatibilies between the new
opencv and gnome-mousetrap. There is a bug filed upstream. I suggest wait and
see if upstream is able to propose a fix soon.

 * sitplus
The FTBFS related to opencv is fixed in Debian version 1.0.1-3. The other FTBFS
cause is a bug in bluez, LP #927097.

So basically, digikam is still TODO, gnome-mousetrap is the real problem :), and
sitplus shouldn't cause any trouble once a fix for bluez is uploaded.

If no one shouts, I will therefore push opencv 2.3 into precise tomorrow
afternoon (that is Monday afternoon UTC+1), and upload the rebuilds and fixes
for the related packages once it's built.
