Ah! Thanks for the info! I assume, you meant 3.4. That (mixed up with
other reasons) might be the main reason for our trouble.

For zope.app.publication there is no newer version, I'm afraid. But, as
I believe now, zope.app.publication is not to blame. Please see below.

Checked it: no problems there :-)
To summarize: zope.app.error 3.5.1 seems to be needed.
After digging deeper: the problem seems to happen when authentication
takes place and it seems in fact to result from different zope.app.error
Luciano: if you try to fetch any non-existent or 'forbidden' page, you
should get the same error. So, it is not admin-UI specific :-)
The error only happens when zope.app.error < 3.5.1 is used. Luciano,
reading your commandline dump I assume, you used a grokproject
environment (and not a trunk checkout), right?
When using grokproject, it seems that zope.app.error 3.4.1 is picked by
buildout, which gives the lookup error. Because I am a buildout
illiterate, I do not understand completely why with grokproject this old
version is used, even if 3.5.1 is installed (and marked stable).
Well, it might be caused by the fact, that in the buildout.cfg template
of grokproject http://download.zope.org/distribution/ is given as link
source and on this list, the 3.5.1 version is still missing (on
http://download.zope.org/ppix it's available).
The grok trunk itself pinned version 3.5.1 for zope.app.error, so here
the error does not happen (good job, guys!).
zope.app.error = 3.5.1
into my grokproject's buildout.cfg and running::
