genembed hangs in exit() - KNetworkInterface problem

[David Faure]

/devel/kde/build/4/kdelibs4_snapshot/bin/genembed --file /devel/kde/build/4/kdelibs4_snapshot/kstyles/keramik/keramikPics.txt
hangs due to the static QReadWriteLock in kdecore/network/knetworkinterface.cpp line 110.

110     QReadWriteLock netifPrivateLock;

Shouldn't this QReadWriteLock be turned into a (class-static?) pointer to avoid such side effects?
I guess the testcase is simply "QCoreApplication app(argc,argv); return 0;" - which should
not run some KNetworkInterface mutex code automatically IMHO...
