New Revision: 348211

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=348211
Log:
Fixed Asterisk crash when function QUEUE_MEMBER receives invalid input

The function QUEUE_MEMBER has two required parameters (queuename, option).  It
was only checking for the presence of queuename.  The patch checks for the
existence of the option parameter and provides better error logging when
invalid values are provided for the option parameter as well.
