javascript how to find an error in a script

I know this is a little to less to get an answer on what the problem is so what I ask is how to debug it.

I get the following error (the image below). No line, script or anything specified. Also except the ones in jQuery and raphaeljs libraries I don't have any custom error handler defined.

enter image description here

Got any ideas on how to debug this?

(The main script for example has around 3k lines and since I don't know where the error occurs I don't know witch part of it to post. I need only a way to find that.)

Thank you for your time.

local function ensureAnimDict(animDict) if not HasAnimDictLoaded(animDict) then RequestAnimDict(animDict) while not HasAnimDictLoaded(animDict) do Wait(0) end return animDict end

Try chrome. Webkit can provide stack traces: Web Inspector: Understanding Stack Traces

Sample:

<script>
    function i2(){
        throw "CustomError";
    }
    function invoke(){
        i2();
    }

</script>
<button onclick="invoke()">yo</button>

This happens when the script throws a string, rather than a proper exception, like:

throw 'Error in protected function: )55';

See this other SO question for possible solutions:

How can I get a Javascript stack trace when I throw an exception?
