[Zope] Input/output error w/ Portal News Items

[ralf.herold@charite.de]

Hello,
after having moved to Zope 2.2 and fiddling with updating a Portal based on
the PTK, I get rather strange errors when trying to read a news item. (I am
posting this to both mailing lists because I do not know which one this
error could related to.) There is _no_ error immediately after restarting
the Zope, but after several seconds/accesses, the error message below
raises. Additionally, there is _no_ error when I access the very same item
as a registeres Portal user, but it raises again if tried to access as
(anonymous) guest.

Error Type: IOError
Error Value: [Errno 5] Input/output error

with the traceback

Could you help to correct this, please? Are there any proxy roles to be set
(I tried manager on recent_news and others, but none worked)? My
installation includes a SiteRoot and TransparentFolder, and was ok before
the upgrading (which apart from above is marvellous!).

Thanks! -- Ralf Herold
