I got this particular error while trying to run Pelican to output HTML on the imported articles from Wordpress.

  |   File "/usr/lib/python3.5/site-packages/markdown/extensions/attr_list.py", line 35, in   _handle_double_quote
  |     k, v = t.split('=')
  | ValueError: too many values to unpack (expected 2)

After some digging around, I found out that the problem is with the Markdown library used in Pelican. Specifically, in the attr_list extension. After careful examination, I found out that presence of \n characters in the inline attribute list produced by pandoc (which is used by pelican-import to convert HTML documents to markdown for editing) is responsible for the problem. So, I have opened an issue. Let me see how it goes.

Now comes the hard part of waiting for the maintainer to look over it and respond. Keeping my fingers crossed.
