Xubuntu 12.04

I initially ignored the popup about a partial upgrade, but curiosity got the better of me and I followed it through. What did it do?

It reinstalled all the core desktop software for Xubuntu that I had un-installed because I didn't need it (e.g. gmusicbrowser, thunderbird, abiword, software center) and then uninstalled xbmc that i had setup through the proper xbmc ppa. No choice in the matter, once I had started that was it.

The partial upgrade was about something, not sure what, possibly XBMC ?

Anyway, got a bit of tidying up to do now the uninstall all that was re-installed and get XBMC back on track (hopefully all config and library files are still in .xbmc)

Anyone else seen something like this ?
