On a semiprivate site sent to me by someone, I get the following assertion failure in debug builds: ASSERTION FAILED: [NSView focusView] == self (/Users/Cameron/OpenSource/WebKit/mac/Plugins/WebBaseNetscapePluginView.mm:600 void -[WebNetscapePluginDocumentView restorePortState:](WebNetscapePluginDocumentView*, objc_selector*, OpaquePortState*))
Created attachment 24873 [details] Stack trace Here is a stack trace. I will try to produce a reduction, preferably one that can be posted on a public bug tracker.
This was fixed by r38081.
