Comment 3 Aleksey 2012-06-17 04:57:42 UTC 
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.
Comment 4 Hugo Pereira Da Costa 2012-06-18 15:32:40 UTC 
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
Comment 5 Aleksey 2012-06-18 15:43:40 UTC 
I found that installation of all soprano libraries from Unstable:SC OpenSuse repo fixes the problem.
Comment 6 Hugo Pereira Da Costa 2012-06-18 15:44:18 UTC 
yes exactly.
Just like mentioned in the thread I linked

Comment 8 Aleksey 2012-06-23 12:00:31 UTC 
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
