[Zope-CMF] Problems with Blark (CMFOptions 1.2, CMF 1.2, Zope 2.5.0, Python 2.1.2)

[David Negaard]

On a fresh install of Zope, CMF, and CMFOptions, and after following the
instructions in the README.TXT file to install/enable Blark, I'm getting
the following error when I attempt to edit a Blark in 'my stuff':

	Site Error
	An error was encountered while publishing this resource.

	Key Error

	Sorry, a site error occurred.


I've started from scratch twice, with the same results. Can anyone help?

I saw mention in the archives of the same problem, and the individual
who encountered it got around it with a fresh install. He hypothesized
that it had to do with UI tweaks. I also installed CMFPlone - could that
be contributing to the problem?


The traceback is as follows:
