Hi all,
We're in the process of migrating our sites to 2.7, so to get the guys up to speed we picked a site at random today. Did the /usr/local/zope/bin/mkzopeinstance.py jig (works very well), copied the Data.fs, some external methods, a Zwiki product and were good to go. This is from a Zope-2.6.1 site.

We found out that LocalFS needed updating, so found a 2.7 compatible version and installed that.

Now we have a very peculiar error, that I'm not posting to the Zope list as it's the RC2 version of Zope2.7 that we're using.

We have an index_html (initially DTML document, then tried method) that can be created (located at /prototype/myporfolio/index_html), have it's security settings changed quite happily. Then when the object is called we get the error in the subject line. The system specs are;

Zope Version (2.7.0rc2, python 2.3.3, sunos5)
Python Version 2.3.3 (#3, Jan 23 2004, 13:36:43) [GCC 2.95.3 20010315 (release)]
System Platform sunos5
SOFTWARE_HOME /usr/local/zope/lib/python
ZOPE_HOME /usr/local/zope

and the traceback is;

Traceback (innermost last):

I have never seen anything like this from Zope before (been using it since 1.0.3 so I've seen it do quite a bit! :).

I've looked through the zope-dev archives and can't find anything related (unless it's got something to do with manage_page_charset not being callable? The only thing I could find on the collector was issue 381, http://collector.zope.org/Zope/381 'HEAD request method broken' - but that doesn't seem relevant in this condition.

*Any* thoughts would be gratefully received. To recap, we took a pretty plain 2.6.1 site, loaded it into 2.7.0rc2 and get the traceback above...
