Hi,

I received an error when I was trying to view the details of existing workflows through API.

I can see 4 workflows owned by myself successfully. But viewing the details of any workflow got me a 500 error.

./display.py <my_key> http://galaxy.nbic.nl/galaxy/api/workflows

Here is the error message in paster.log:
/*

*/

Any suggestion on how to solve this problem?

Thanks,
