I can confirm that in kde 4.8.4 nepomuk controller crashes every time when clicking on it. In KDE 4.8.3 nepomuk controller worked fine. OS: OpenSUSE 12.1 64 bit.
I believe this bug is related to thread below: http://lists.kde.org/?l=kde-core-devel&m=133970243712079&w=2 stability issues with nepomuk due to "threading" as far as I understand. Nothing to do with oxygen (rather memory corruption), and definitly not a dupplicate of bug 258565
I found that installation of all soprano libraries from Unstable:SC OpenSuse repo fixes the problem.
yes exactly. Just like mentioned in the thread I linked

After last update from OpenSUSE repo (http://download.opensuse.org/repositories/KDE:/Release:/48/openSUSE_12.1/) nepomukcontroller crashes no more. So, for OpenSUSE the bug is fixed :-)

This issue no longer occurs with KDE 4.9
