Jokosher not running

I installed Jokosher from the Pacman repositories and when I go to run it, nothing happens. Suggestions?

Thank you!

This is the error message I get in the terminal:

/usr/bin/python: symbol lookup error: /usr/lib/python2.5/site-packages/gst-0.10/gst/_gst.so: undefined symbol: gst_parse_flags_get_type

Anyone, help please?
