Bug 206045

Application that crashed: konqueror
Version of the application: 4.3.00 (KDE 4.3.0)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I opened a set of bookmarks using the "Open Folder in Tabs" feature. One of the pages caused a redirect from HTTPS to HTTP, causing an "about to leave secure mode" dialog to come up.  If I click "Continue Loading" soon, things work as expected.  However, if I'm busy in another application and don't dismiss the dialog for a few minutes, Konqueror crashes immediately.
