Version:           3.5.8 (using KDE 3.5.8, Kubuntu (gutsy) 4:3.5.8-0ubuntu3.1)

OS:                Linux (i686) release 2.6.22-14-generic

When trying to book a flight at www.der.de, using the quick form on the right side, I've got to confirm that I want to indeed submit the form to an unencrypted site. No surprise so far, that's the intended behaviour.

However, directly afterwards, another such dialogue comes up, while in the background the new page has loaded already. Trying to get rid of the dialogue either way makes konq crash.
