a small puzzle re. upgrading to slávek's repository

greetings, good people!

my notebook machine now working properly for the first time in months through the upgrade to slávek's repository, i thought to do the same with my desktop machine (also running kubuntu 12.04) but even apt-get dist-upgrade holds back kdelibs-trinity. it's d/ling right now and i have a sense that i may be about to break things.

am i right in assuming there is something wrong/i am doing something wrong here?

thanks for any ideas that might be forthcoming.

best,
