Version:            (using KDE KDE 3.5.5)
Installed from:    Ubuntu Packages

Clicking "Close this Window" on the "Manage Attachments" page of vBulletin makes Konqueror (3.5.5) crash. I can reproduce this on qtcentre.org (vBulletin 3.6.3) and ubuntuforums.org (vBulletin 3.6.4). On QtCentre the problem occurs every time, but on Ubuntu Forums it only happens like every third time.

1) Make a new post
2) Press "Manage Attachments"
3) Press "Close this window" (either the link at the top or the button at the bottom)
