PluginInstanceChild::ClearAllSurfaces() calls PPluginSurfaceChild::Send__delete__(), but I think it fails because we're already in some kind of shutdown or error state.

I see 195 crash reports with this signature.

This should only be for the new async drawing mode which is in Flash betas but not Flash release. dvander?

Comment 4

[Andrew McCreight [:mccr8]]

72% of these crashes are with Flash version 21.0.0.242, which looks like the current version you can download. (Another 17% are on 21.0.0.213.)

It looks like this predates direct drawing. We're trying to send a __delete__ message over IPDL, but sending anything after an ActorDestroy will trigger a MOZ_CRASH. I think we can just set these actors to null so PluginInstanceChild doesn't try to access them again.

Don't try to send PPluginSurface::__delete__ within ActorDestroy. (bug 1279340, r=bsmedberg)
