I was reading bugtraq today, and noticed that safari has a javascript bug that can cause the browser to crash. Just thinking to myself, I would have to think that this issue would cross over to other applications that use the WebCore engine that safari uses.
Interesting point to note, Konquoror (3.1.93) - which uses the KHTML/KJS engine that Safari uses - crashes with an error. Errors are better than full out crashes.
A script on this page is causing KHTML to freeze. If it continues to run, other applications may become less responsive.
Here is the article for any of those that are interested.
