QCoreWlanEngine is leaky on Mac

When starting Qt Creator on MacOS, I get:

2010-04-28 16:19:43.191 Qt Creator[29578:a0f] *** __NSAutoreleaseNoPool(): Object 0x11c9789f0 of class NSCFArray autoreleased with no pool in place - just leaking

Setting a breakpoint on the function mentioned (that is: __NSAutoreleaseNoPool) tells me:
