Details
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150611135623
Steps to reproduce:
In bug 1050691, I use this workaround to access the Debugger.Script object:
> + let script = dbgGlobal.makeDebuggeeValue(obj.unsafeDereference()).script;
where |dbgGlobal| is the thread actor debuggee global and |obj| is the Debugger.Object instance of a function. Just calling obj.script returns null, and according to :fitzgen, that's unexpected.

Glancing at Debugger::wrapDebuggeeValue, we don't seem to do any kind of unwrapping, which may be the issue here.
Summary: Debugger.Object.prototype.script is null if the object has not been instanciated with the referent function's global Debugger.Object → [jsdbg2] Debugger.Object.prototype.script is null if the object has not been instantiated with the referent function's global Debugger.Object

BTW, if that's a good first bug, I would be glad to work on it.
