Description Randell Jesup [:jesup] 2013-01-30 07:44:06 PST
When using mozGetUserMedia, if the UI is enabled we leak a copy of every media source device and an nsTArray (and perhaps some related objects).  We don't see it in the mochitests as they suppress the permission UI.

Caused by copying an allocated nsTArray<nsCOMPtr <...> >, which is then dropped on the floor.
