EDIT: So, after some digging around, it seemed like at some point in time I manually installed libopenscenegraph123. Which is why it complained, because the repo did not manage the package, but the update of openmw required it. So, because of the package name difference, it tried to install it on top of the other one.

I resolved this by uninstalling libopenscenegraph123 and then the install of openmw was successful.

Yup, everyone will have growing pains here due to switch from openscenegraph to openscenegraph-3.4. I'm going to modify the title to solved so people can come here to read.

This occurs because of a serious bug in packaging.

For people doing the packaging: here is a hotfix.

When you're done applying it and rolling it out to the PPA, contact me and I'll explain how to handle this properly.

Thanks for that, applied and are building now.

The problem was due to the fact that the old osg-3.4 was just named osg, so there was a collision waiting to happen when we finally synced up with debian using osg-3.4. We didn't know before hand Debian maintainers would do a rename.

Debian decided not to just upgrade the OSG package, but in the spirit of ogre3d (-1.7, -1.8, -1.9) to create a new package with the version post-fixed. The dangerous thing here is that OSG-3.4 still requires openthreads, which is built by the original OSG package. That means that if there are fixes upstream for openthreads, it won't make it back downstream because OSG (3.2) won't be updated, and OSG-3.4 isn't making its own packages for openthreads. *sigh*
