Not a major issue, as rpmbuild appears to cope with it OK, but the source file 'wacom-gui-0.2.0d.tar.gz' in the 0.2.0d SRPM is not a compressed tar file, but actually a zip file ... which is a bit confusing :-)
Fixed in newer release. Renaming a .zip to .tar.gz doesn't make a difference to the RPM build process but I'll try to make sure a tar.gz is not really a zip with future releases.
