I'm getting the following when trying to render a template. Any
suggestions on where I can look to figure out what is going wrong?

File "/home/elis/edit/.../mycontroller.py", line 39, in attachmentList

Hi

It looks like your template has an assingment that is unpacking
something that can't be unpacked, e.g.

```
from genshi.template import MarkupTemplate
m = MarkupTemplate("""<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:py="http://genshi.edgewall.org/"><div py:for="x, y in
l"></div></html>""")
m.generate(l=[{}]).render()
```

Sorry the error message isn't great. Hope this helps.

Helped a ton, thank you! I was able to figure out what I had been messing
up by looking for unpacking (much faster than commenting out lines at
random until the page works again ;).

Cheers,
Eli
