Error: Attempt to run compile-and-go script on a cleared scope

Question

Since upgrading to Firefox 4.0, I\'ve noticed that I\'m occasionally getting an error in the console stating:

attempt to run compile-and-go script on

I've noticed that this error can happen if you write to the document with document.write after the document has completed loading (e.g. in a function called from JQuery's $(document).ready() method). When this happens, it seems that Firefox discards the old document and writes a new one. I don't know if this is new behavior or not. It seems that when you try to operate on the old document, e.g. with JQuery selectors, you get this error. For me, fixing the script in question to not call document.write after the document had loaded fixed the error.
