Bauble does not start from menu in Ubuntu Maverick Meerkat

[Paul A. Drinnon]

Bauble installed from Ubuntu Software Center. Icon in Applications-Education-Bauble. When Icon is selected nothing happens.

Could you start Bauble from the command line and paste the output here.

Also, the version included with Ubuntu is pretty old. Your best option is to install Bauble from the PPA at https://launchpad.net/~bauble/+archive/ppa

Starting Bauble from command line fails with:
