Description Miro Hrončok 2014-01-04 19:03:55 UTC 
Description of problem:
While markdown links in descriptions generally work, if the URL contains colon, the link changes to empty string.

Steps to Reproduce:
1. Put a link with colon in the description (using the markdown syntax)
   such as [Miro](https://fedoraproject.org/wiki/User:Churchyard)

Actual results:
<a href="">Miro</a>

Expected results:
<a href="https://fedoraproject.org/wiki/User:Churchyard">Miro</a>

Additional info: see http://copr.fedoraproject.org/coprs/churchyard/chromium-russianfedora/ for real life example

(I've tested by experimenting, that the colon is the thing that breaks the link, other characters might do the same thing.)
Comment 1 Miroslav Suchý 2014-01-08 15:57:22 UTC 
This is problem of python-markdown.

Reproducer:
>>> import markdown
>>> md = markdown.Markdown(safe_mode='replace',
...                    html_replacement_text='--RAW HTML NOT ALLOWED--')
>>> text = "[Miro](https://fedoraproject.org/wiki/User:Churchyard)"
>>> md.convert(text)
u'<p><a href="">Miro</a></p>'

rpm -q python-markdown
python-markdown-2.3.1-3.fc20.noarch
Comment 2 Thomas Moschny 2014-01-08 16:40:07 UTC 
Upstream says this behavior is intentional: See https://github.com/waylan/Python-Markdown/issues/220
