Just wanted to note that the most basic failing test case is this:

While that does not validate at xhtml it does as html4. Seeing we have a built-in option to output html4, it should work. Besides as the reporter noted, other implementations don't stumble over this so neither should we.

Here's the relevant debugging info:

>>> import markdown
 >>> t = '<img title="foo"> src="">'
 >>> md = markdown.Markdown()
 >>> md.convert(t)
 u'<img title="foo"&gt; src=""&gt;'
 >>> md.htmlStash.rawHtmlBlocks
 [(u'<img title="', False), (u'', False)]

The entire string should be one rawHtmlBlock. It would appear the raw html block parser is ignoring the quotes.
