Ark - doesn't open in KDE4

I downloaded a zip file and tried to open with Ark, but the Ark window opens with nothing in it! Doesn’t Ark work in opensuse 11 KDE4? I can open the contents of the zip file by just double clicking on it, but why doesn’t Ark work?

I guess we have to wait until KDE 4.1 comes out, 4.0 is pretty but disfunctional at this point.
