Description of problem: After installing psi (yum install psi qca-tls) and starting it under the default installation of gnome the program looks as if it is using the motif widget style and does not look at all as if it is using the gtk style. The installed component is psi-0.10-5.fc6. Please see the attached screenshot.

Psi is a QT application, and thus will not use the GTK style. However, QT sould not use the motif style by default. Please run "qtconfig" and in the first box ("GUI Style"), select "Plastik". That should give you a theme close to Clearlooks on GNOME.
