cfn/F17/WordPress_Single_Instance.template returns"ERROR: in <"byte string">, position 0"

[Angus Salkeld]

So this might be a heat bug, but looks like some odd character in the template.

This template is referenced in the devstack tutorial it really needs to work!

Some more debug:

So the problem is in heat/common/urlfetch.py

If I make the following change this problem goes away:
diff --git a/heat/common/urlfetch.py b/heat/common/urlfetch.py
index 02e75cf..228f46f 100644

    Prevent urlfetch from returning encoded chars

    raw.read() is returning unprintable characters. Iterate over the
    decoded characters instead.
