No problems here: OS X 10.9.1. It didn't start right away because of the new protection in OS X 10.9 involving the 'registered developer' thingy, but other than that I copied it to Applications and it just starts. No problems with the zip. You could try downloading and unzipping it again...

When I attempt to open the unzipped BaseX.app (version 7.7.2), OS X reports that it is damaged.
