The error message is quite uninformative, it is something like: "uncaught exception: out of memory error". Obviously this makes finding the error quite hard. We should either improve the error or automatically use the |buffer| property of the Uint*Array.

I'd expect an NS_ERROR_FAILURE exception, not something about "out of memory"... The right solution here is to make this a Web IDL API, by the way; that will get you sane error reporting for free.

See also bug 1057538, where the NS_ERROR_SOCKET_ADDRESS_IN_USE error isn't propagated. I guess something similar is happening here. I remember fixing a similar bug for mozApps.
