Yes. We've seen that problem. It happens because:

 * Soprano uses a namespace
 * Soprano defined qHash(Soprano::Node) before qhash.h was defined
 * qvariant.h has changed in 4.5, including qhash.h now

That means the definition for QHash jumped above the definition of the 
qHash function. You have to put the function inside the Soprano namespace 
for this to work.

According to our expert, this is the way the C++ name lookup rules say it 
should be.
