Without this crash, DumpRenderTree does this ever time I run it:

Patch
What do other ports do?
The only other port that calls WebCore::provideUserMediaTo() is Mac (WebView.mm, line 937), and I'm not sure why the assertion doesn't fail there. I don't know what changed, but this isn't crashing anymore. |
