CustomSearchControl: script errors in IE8 (exceptions not caught)

[GoogleCodeExporter]

In Internet Explorer 8, submitting queries to the Custom Search Control may 
cause errors (exceptions not caught) in ads-related scripts.

This issue was originally reported by 2 users in the Custom Search help forum.  
Here is the original thread:

http://www.google.com/support/forum/p/customsearch/thread?tid=3a329136cdfaa854

The original reports describe two error cases: one that may occur on an initial 
search, and another that occurs on subsequent searches.  In my initial testing 
I have observed only the latter case, using IE8 version 8.0.6001.18702 in 
Windows XP.  (If I get a chance later I'll test again with a more recent 
version of IE8.)

To demonstrate the problem please follow these steps:

1)  Implement a simple test page using the Custom Search Control on any CSE.

2)  Put the page on a remote web server. *

* (Note:  If you test the page "locally", IE8 might hang when you submit a 
query.  That may be a separate problem which may also be worth investigating.  
For our current purposes please test remotely.)

3)  In IE8, click "Tools" > "Internet Options" > "Advanced".  Enable the option 
to "Display a notification about every script error."  Also enable script 
debugging (remove the check-mark on "Disable script debugging (Internet 
Explorer).")

4)  Visit your test page in IE8, and submit a search query.  The first query 
may or may not produce an error in a script named "searchframe.I.js".

5)  Submit a second query, and observe an error in a script named 
"search.I.js".  Subsequent queries may again produce the same error.

Note:
The browser's error messages indicate exceptions thrown but not caught.  
Investigation in the script debugger may suggest that these might be 
permission-related errors possibly associated with HTML5 messaging.

Typo Correction:

In steps 4 and 5 of the procedure above, I mentioned the names of two scripts.  
In step 4, the script name is misspelled.  The correct spelling is: 
"searchiframe.I.js".

This seems to happen in Firefox, too (v3.6.10), whereas Safari seems unaffected 
(v5.0.2).

My CSE has ads disabled because it's for a non-profit organization: don't know 
whether that has anything to do with the reported behaviour.

I am having the same issue (Message: Exception thrown and not caught Line: 12 
Char: 117) but it is occurring in search.I.js. It works fine in Firefox 3.6.11 
and Chrome 7 but not IE8. My CSE has also ads disabled due to its non-profit 
status.

I'm having the same error:
"Exception thrown and not caught"
search.I.js
line 12 character 117

When I'm trying to view 
"http://code.google.com/intl/el-GR/apis/ajaxsearch/documentation/customsearch/" 
from IE8.

FF, Opera, Chrome works fine.
