Hi there, The KDE 4.10 transition to testing is currently a bit confused.
I tried updating my testing box this morning, and apt wanted to uninstall most of KDE. I tracked the problem down and nepomuk-core-data (src nepomuk-core) breaks kde-runtime-data (<<4.8.80) (src kde-runtime). The problem is that kde-runtime 4.10 has not made it to testing yet, so apt wants to remove kde- runtime and everything that depends on it. Pretty much all of kde depends on kde-runtime. -- Mark Small
