oh, thanks for the comprising debug info...
yes, the first error might not be crucial...
i think i tracked down the reason, its due to some new code-inline-image feature i'm currently testing. some lines too long in the shader code - firefox doesn't seem to like that... i'm on it...
and the socket stuff is for remote osc-connections (you'd have to start a small server-script locally to use that - see shaderoo help-page)
