No, honestly. I haven't heard of that error before and there's not much information there that could help narrow things down.
Can you tell me when you're getting that error? Is it during the installation process, after the install, in the admin area or the front-end area? Also, if you disable the JFBCSystem plugin, does the problem go away?
Let us know any details you can and we'll gladly help investigate further.
Thanks,
Alex
