Console message: [JavaScript Error: "Error: operation not possible on dead CPOW" {file: "resource://gre/modules/RemoteAddonsParent.jsm" line: 575}] is rather suspicious here, but perhaps that could be from the previous page unloading?

Is this a known error message on other tests? Despite the common problem of having plugin tests time out, this particular error seems unlikely to be a plugin bug.

The 10 previous runs of this test suite didn't show the error message about the dead CPOW. Afaik RemoteAddonsParent is a general shim for CP calls.

What would it take to get a stacktrace for the dead-CPOW warning?
