Thank you for reporting this bug. I can confirm this on an up-to-date version of Karmic. Pressing the up and down arrows continuously to navigate through the sidebar crashes the applications after you've gone over a few items. I'll check upstream and either link it to an existing bug report or submit a new bug.

Upstream figured out this actually is a WebKit bug. It should have been fixed by this changeset: <http://trac.webkit.org/changeset/51380> and thus in WebKit 1.1.17.

[Sense Egbert Hofstede (sense)]

I set this bug to Fix Released since this should be fixed in the current development focus: Lucid Lynx.
If you are able to still reproduce this bug with the latest version of WebKit in Lucid, please reopen this bug.
Thanks to all for your participation!
