iphone - very strange thread error message -

I am trying to put a method in a different thread in the background. It almost works except that sometimes I get a lot of error messages with the message

  Method code: oh bad spelling and nothing with nothing  

Does anyone know what this means? Thread runs interestingly

More specifically: I

  [object] with self performSelectorInBackground: via @selector (finishedRunningThreadData :);  

method

  - (empty) CompletionTradedata: (NSString *) and {NSAUTOriospool * pool = [[NSAUTOriasPool Alok] INS]; // call iPhone-wax methods which can call objc thread [pool release]; }  

Answer: The error message comes from wax-iphone, it first checks to see which thread is going on (wax-instance.h line 337)
