2. Go to http://www.excite.com/
3. Click on "My Email"
4. Login into your account using secure option (if no automatic login has been arranged), confirming changing from a https to a http page
5. During the load of the web interface (the load bar showing the precentage of the load) a crash happens
The unexpected termination was noticed by KDE, and a stack trace was produced:
