Markdown - IndexError: list index out of range

[pwalsh]

Background

I'm seeing a range of simple exceptions coming out of datahub.io (running CKAN 2.4). These errors are not critical, but should be addressed and are probably easy "good for contribution" tasks.

Browser: Googlebot 2.1
URL: http://datahub.io/dataset/nalt

Issue

not sure this is a ckan issue, but looks like it is as the markdown lib is called from the core ckan lib.
