[galaxy-user] Error on custom builds on public galaxy server

I am having a problem with the public galaxy server. When I try to go the User->Custom Builds page, I see the following error:

-- Server Error

An error occurred. See the error logs for more information. (Turn debug on to display exception reports here) --

I had previously created a custom build but when I try to use it, for example in a BWA/Illumina alignment, I get the following error:

-- Error executing tool: maximum recursion depth exceeded while calling a Python object --

I believe this is a continuation of a previous thread that was started before I joined the list:

Thanks for any help.
