Source/WebCore:

Chromium has a refptr that needs to be NULLed at this point.

The approach is to change the client redirectDataToPlugin method(s) to expect
the possibility of a NULL argument, and the use this to clear the refptr on
the chromium platform.  Other platforms can merely ignore the NULL case, thereby
maintaining the existing behaviour.

Formal testing is nearly impossible without some chrome-specific plugins.
