bind() exception in IE8 for popped out window

bind() exception in IE8 for popped out window

I recently upgraded from JQuery 1.3.2 to 1.4.2.
 
I have a page which opens a new window.  There is a javascript object in the parent window which, as one of it's properties, contains a function.  As part of the popout process, the child window is given a reference the object's function.  In version 1.3.2 everything worked as expected.
 
In version 1.4.2 under IE8, a call to 'typeof' on the function reference reports that the function is an object.  As a result, an error is thrown on line 1572 (uncompressed).
 
I have found reference online about IE8 doing cross window conversion from functions to objects, but nothing specific to this case.  I have also tried versions 1.4 and 1.4.1 with similar results.  While I could alter my code to make the function call local to the child window, it would be preferable to keep the function in the parent for reuse purposes.
 
I am at a loss and any help would be greatly appreciated.
