This fixes http://code.google.com/p/chromium/issues/detail?id=493, which
was a crash in the 3dvia plugin. A script on the page tries to interact
with the plugin by obtain its npobject. The plugin's does not implement
the corresponding NPP_GetValue function correctly and returns NPERR_NO_ERROR
without filling in the NPObject pointer passed in.

The fix is to initialize the NPObject pointer on the stack to NULL and
check for this along with the error check.
