Aside from that, and the problem with '#quotes' as Andrew pointed out,
absolute_url() is just not safe to use with restrictedTraverse(), since
the url takes virtual hosting into account and thus may add or remove
parts of the path. This technique tends to work fine during local
development and then as soon as you deploy to a server with virtual
hosting configured, boom, everything breaks. No fun.
So, Don't Do That.
See http://www.plope.com/Books/2_7Edition/AppendixB.stx#2-394
When creating paths for use with restrictedTraverse(),
you should always use getPhysicalPath() instead.
In this particular case, I suspect you don't even need to do that.
Try:
tal:define="root python:here.restrictedTraverse('index_frame.pt')"
which can be spelled a bit more simply as:
tal:define="root nocall:here/index_frame.pt"
