Ticket Information

Ticket Title

In a plain text file add a "*", then a space, and then a tab. Add another star, a space, and another tab. Save the file.

Run markdown on it. I get:

Traceback (most recent call last):

    IndexError: child index out of range

I found this because one of my editors mistakenly wrote in a horizontal break using "*  *  *" but varied between spaces and tags. Kind of an esoteric scenario, but it crashes django.

Thanks for all the work on the library,

Silvio

Hmm, I can't seem to reproduce this. Could you provide the exact input which caused this? Thanks.

For example, trying this in the python interpreter raised no errors:

>>> import markdown
    >>> markdown.markdown('* \t* \t')

Granted, the output is a little strange, but nothings crashing as you say and it's enough of an edge case I'm not to worried about the odd output. However, if you can provide something that crashes Markdown, then we definitely want to fix that.
