[Plugin: WP E-Commerce currency helper] Errors, missing graphics

I tried installing with the latest versions of WPEC and WP, and the plugin works as it does perform an ajax call and converts currency on the fly. There’s a problem with missing pieces of the bubble image though, and it seems to exist for every theme selection.

Error sample:

It looks like an object isn’t being handled properly and might be recursing into code.
