[STR New]

When trying to print from Mac OS X Lion with the included CUPS build (I
guess 1.5rc1), printing to certain SMB servers crashes the SMB backend.
This behavior was not exhibited under Mac OS X Snow Leopard. This behavior
is exhibited attempting to print to printers hosted on WS 2008R2 with
authentication being required. I do not see this behavior exhibited on any
other Windows version.
