Users are getting the following error when trying to add a tool from the tool shed repository on our local galaxy instance.

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

The galaxy server log shows the message included below. The main error is "ValueError: too many values to unpack ". From a similar previous post, the resolution was to use the latest code from Galaxy central. I just ran an "hg pull -u" pointing to galaxy-central (we had been pointing to galaxy-dist), but we still get the same error.

Any ideas?
