It seems a bit odd that we are getting the scriptable object in this 
case, but in general plugins should expect to receive nested calls 
(except for NPP_Destroy) and be prepared to handle them.

It sounds like this could possibly be related to the plugin process 
implementation in Firefox 4, but we turned that off for Java plugins 
because of persistent bugs, so it shouldn't be an issue.
