System Testing (aka checkbox-gtk) fails to run

When attempting to run system test in Oneiric nothing happens, same from the command line. After running from the terminal: checkbox-gtk -l /tmp/cbox.log --log-level=debug I get tracebacks

2011-09-03 10:46:16,107 ERROR Error running event handler /usr/share/checkbox
