Setting TXT records with CFNetService

Hi,

I can't get CFNetServiceSetTXTData to work.
If I call it before CFNetServiceRegister, my app crashes when calling CFNetServiceRegister with this in console.log:

*** -[NSCFData _fastCharacterContents]: selector not recognized [self = 0x3c5850]
*** Uncaught exception: <NSInvalidArgumentException> *** -[NSCFData _fastCharacterContents]: selector not recognized [self = 0x3c5850]

...and this is from the actual crash log:

Thread 0 Crashed:
0   com.apple.Foundation               0x92897200 _NSRaiseError + 264
1   com.apple.Foundation               0x92896f3c +[NSException raise:format:] + 40
2   com.apple.Foundation               0x9287006c -[NSObject(NSForwardInvocation) forward::] + 176
3   libobjc.A.dylib                    0x909b10d0 _objc_msgForward + 176
4   com.apple.CoreFoundation           0x9072946c __CFStringEncodeByteStream + 100
5   com.apple.CFNetwork                0x90f23178 CFNetServiceRegister + 348

If I instead call 'SetTXTData after 'ServiceRegister, nothing crashes, but the TXT records are not broadcasted.
I have tried both creating the TXT data with CFNetServiceCreateTXTDataWithDictionary, and creating it myself. Both conform to the specs, and look fine.

So my question is: How do I set TXT records with the CFNetService API?

Thanks,

Tomas Franzén
