Fix bug #6950: Cursor remains in waiting state after incompatible command.

Browse Source 
P.S. How do we prevent other cases like this? By throwing exceptions, we never know whether it's assured that we will return to the function to call setBusy(false). In JAVA you always have to either make a function throwable or to catch the exception, but AFAICS you have to crawl through the code to find out whether a function can throw an exception.
