(This is the proper log message for r17778)

Denis reported that receive(0) returned messages.

This bug is present in the Db & Array adapters.

This has been fixed in all adapters.

In Zend_Queue 2.0 we need to make a requirement that all messages must be 0 
or higher and negative numbers will throw an exception.
