User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.3) Gecko/20060426 Firefox/1.5.0.3

If an exception is thrown while in the onDrop function, the browser will start to load the transferData as a url into the browser.  The url it loads depends on what text is in the transferData.

I will attach a sample test case shortly.

Reproducible: Always

Steps to Reproduce:
1. Open test case in chrome.
2. Perform drag and drop operation.  Exception is thrown manually in the code.
3. Get redirected to a url.
Actual Results:  
Get redirected to a url.

Expected Results:  
Don't get redirected.

The new drag and drop api added in bug 356295 makes nsDragAndDrop.js obsolete.
