Welll....the thing is that the links you provided are about a different error. These are related to a taglib1 problem, but mine is related to plasma. And it is only opensuse users that are affected as far as I know (at least that is how much I found out from bugs.kde.org) And Opensuse forums are also suggesting removing of the config files which doesn't work in my case.
I am still trying to find the solution.
(quite interesting because i neer have been into debugging problems much, got on the bus only when bus when my amarok broke
)
