If you're comming here from google and are looking for an easy solution to fix this problem in IE:

In our case the problem occured, because we were working with events inbetween iframes. By doing so it was possible that, upon changing the iframe contents combined with a triggered event it would attempt to call the script on the now changed iframe document. this raised the exception in question.

by adding

$(window).on("unload", function(){
    $(target).off(eventname, handler);
});

the problem would cease to be raised. Finally no try/catch because of IE.
