Hi all, 
We are just about to enable the Toolshed on our development installation of Galaxy. 
We run the latest build (rev. b258de1e6cea) of Galaxy. 
Our workflow is the following: 
- On the admin panel, click 'Search and browse tool sheds'
- 'Browse valid repositories' on 'Galaxy main tool shed'
- Select any tool and 'Preview and install' 
- 'Install to local Galaxy'
What we see on the website is:

The apache error log says:

Any ideas and/or hints? 
Thanks a lot for your help!
