Status: RESOLVED WONTFIX

(Core :: XPConnect, defect)

Description

[Ben Turner (not reading bugmail, use the needinfo flag!)]

This line:

var foo = XMLHttpRequest.prototype.send();

causes this:

Error: uncaught exception: [Exception... "Operation failed because the XPConnect subsystem has been shutdown"  nsresult: "0x80570033 (NS_ERROR_XPC_HAS_BEEN_SHUTDOWN)"  location: "JS frame :: javascript:var%20foo%20=%20XMLHttpRequest.prototype.send(); :: <TOP_LEVEL> :: line 1"  data: no]

I'm not sure what the right fix is though. peterv?

I don't think we care about quickstubs edge cases at this point.
