that's definitely it.

the old package is from the marillat repository, way back when.  Clearly
there was some disagreement about its version number, and Christian
Marillat assiigned it a sensible-sounding 1.0alphaX -- but the Ubuntu
packagers later decided on a much lower version for their package.

I must have had the marillat apt repo in my sources.list at some stage.

sudo apt-get remove libtheora0 , then a sudo apt-get install of all the
packages that that removed, fixed it.

Thanks Stephen!
