Comment 1 Dawit Alemayehu 2012-05-26 14:20:04 UTC 
Can you provide a link with which this can be reproduced ? It seems like the crash happens when a KIO warning message box was about to be shown.

konqueror (4.8.4 (4.8.4) "release 513") on KDE Platform 4.8.4 (4.8.4) "release 513" using Qt 4.8.2

I hit the same problem. I was surfing userbase.kde.org and then tried to authenticate with my OpenID. Instead of asking me for the credentials or anything it just crashed.

konqueror (4.9.00 "release 559") on KDE Platform 4.9.00 "release 559" using Qt 4.8.2

What I was doing when the application crashed:
- Opening a link in a new tab on save.tv.

Seems unrelated to a "KIO popup" as suggested in earlier comment.

Comment 4 Christoph Feck 2012-09-01 14:10:58 UTC 
> Seems unrelated to a "KIO popup" as suggested in earlier comment.

Look at your backtrace, it calls KMessageBox from KIO. You probably have the "Do not show this warning again" checked once, so the box won't appear any longer.

I still get the crash daily, when going from https to http twice (e.g. when viewing two attachments in bko).
