Valgrind qtconfig trace

Description of problem:

Worked fine until a little over a week ago.  I can no longer launch a KDE session with kdm or gdm.  Any attempts to open a KDE or Qt app from within Gnome yield:


$ kopete
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
kopete(11090): Communication problem with  "kopete" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" " 


Please see attached traces of qtconfig.

Here is my Smolt profile: http://www.smolts.org/client/show/pub_a686b807-e8c2-421c-ac42-54b5d1deae6c

I am not using any 3rd party dirvers, just the FOSS radeon driver.
