NSConditionLock console message: "unlocked from thread which did not lock it"

Hello All,

Under Leopard, my application has begun logging console messages like this:

2007-11-25 09:09:03.572 Script Debugger 4[66788:613] *** -[NSConditionLock
unlockWithCondition:]: lock (<NSConditionLock: 0x2b5e7ed0> '(null)')
unlocked from thread which did not lock it

The message is correct: I lock the NSConditionLock from a worker thread to
block the thread until another thread (the main thread) receives a response
and the worker can continue on.

This seems to me like a legitimate use of a lock.  Can anyone explain what
the problem here is.

Cheers
-Mark
