I have read elsewhere that you can edit "/usr/share/themes/QtCurve/gtk-2.0/gtkrc" and add a line to change the default fonts.
I think the problem for Kubuntu users is that OpenShot has a dependency on Gnome libraries, yet the KDE desktop does not come with Gnome libraries installed.
I was unable to use Gnome's Shutter (Perl-based) screen capture application under KDE because of this issue.
I have not yet verified whether the following fix will help with OpenShot:
1. Run: sudo aptitude install desktop-file-utils perl-modules libnet- dbus-glib- perl gnome-settings- daemon daemon
2. Run: gnome-settings-
3. Run: openshot

Hope it helps!
