Review request for Nepomuk, Vishesh Handa and Sebastian Trueg.


Changes
-------

forgot to remove old code from slotPropertyAdded().


Description
-------

Fix race conditions in nepomuk's ResourceData.

Found with "helgrind kmail --nofork", inbox, clicking on any email.
where helgrind is "QT_NO_GLIB=1 valgrind --tool=helgrind --track-lockorders=no"

The change in resource.cpp avoids a deadlock due to the change
in resourcedata: no need to hold the rmMutex for the determineUri call.


This addresses bug 295802.
