From https://bugzilla.novell.com/show_bug.cgi?id=462850 The Konqueror "Configure" window is too tall. I am certain there is probably some kind of "Save" button somewhere on the bottom of the window. I cannot see it at all, and of course, cannot use it.
What KDE version (or SVN revision) are you using? Can't you resize the window? This may be related/duplicate of bug 155663
It would be 4.1.3
