I recall that first installing it (python setup.py install), and then
rerunning selftest, solved that error.
I tried that as well.

I have this python list that represets a sitemap:
tree = [{'indent': 1, 'title':'Item 1', 'hassubfolder':False},
{'indent': 1, 'title':'Item 2', 'hassubfolder':False},
{'indent': 1, 'title':'Folder 1', 'hassubfolder':True},
{'indent': 2, 'title':'Sub
Use a stack?
Whenever you start a new list, push the corresponding closing tag onto
a stack. Whenever your indent level decreases, pop the stack and
write out the closing tag you get.
It's straightforward to use a python list as a stack.
Thanks for the tip, Kushal.
