Hi Greg,

Thanks for your answer. I've upgraded my Galaxy instance to 56bdee21dc78 from 
Galaxy central repository.

I tried again to install tabular2html from the tool shed, but I get the same 
problem (Server Error when installing and shed_tool_conf.xml not updated). Here 
is my log in case it helps.
