I see as a problem that you used 'aptitude upgrade' instead 'aptitude 
dist-upgrade'. On my test machine I use aufs, thanks to which I could 
re-testing of the upgrade from 3.5.13.2 to R14.0.0.

In the case of 'aptitude dist-upgrade' on my test machine upgrade always go 
smoothly. Where I used 'apt-get dist-upgrade' there is a problem with 
tdelibs-data, as in your case.
