Bug Description

grok 1.0a4 using paster

When there is an issue in a TAL file, grok does not tell you which template threw the error, or much of any other useful information in debugging the problem.

Sample error message below, which was introduced by changing 'sorted' to 'sortedd' in the line below:

<div tal:repeat="post python:sorted(context['posts'],lambda x, y: int(y)-int(x))">
