Browsing youtube, crashing in the parent:

Here, `object` is 0xdddddddd which means freed memory on Windows. This likely means that the PluginInstanceParent is already freed. I'm trying to think what kind of race would leave an invalid PluginInstanceParent hanging around; nothing comes to mind right now.

I just had this crash on Win7 HP 64bit http://crash-stats.mozilla.com/report/index/7429dfbd-298e-45d6-bcc7-79b622091217 So, OS all?

The only other thing which can destroy PluginInstanceParent other than NPP_Destroy itself is: ActorDestroy (plugin crash, but I don't think that's happening here) or NP_Shutdown. It's illegal to call NPP_Shutdown after NP_Shutdown, so I'm stumped. Maybe need logging if this keeps happening.
