Version: 4.6 (using KDE 4.6.1)
After you enter it incorrectly flogged root in KDE settings, resize the window I was flogged. It increases in length and decreases in height.
In KDE 4.5.5 this problem is absent.

Before the wrong password
Still present in KDE 4.7.4
I can confirm that this bugs still exist on KDE SC 4.9.2. As an additional note, the dialog size changed again after the second wrong password. See screenshot.

*** Bug 354857 has been marked as a duplicate of this bug. ***
The size increasing when additional messages need to be displayed is intended.
The wrong initial minimum size should be fixed in kde-cli-extras master.
As Christoph mentioned, the greater subsequent size is intentional and required, to display the extra text. The incorrect minimum size was recently fixed in Bug 381231.
