Here's an example, almost identical to one that Sebastian mentioned a
couple days ago:
TypeError: unsubscriptable object (see full traceback below)
The real problem is a badly spelled macro invocation. The fact that a
high level activity such as editing page templates generates such
low-level messages as this is a problem. Somewhere along the call
stack that exception should be treated for what it is, providing an
error message with more context.
Cheers,
Luciano
