PLease submit a collector issue at:
A test would be especially helpful.
Yeehaw, I was afraid someone would ask for such a thing.
I must admit I actually wasn't able to write it up to now,
since I'm not too familiar with all the traversal stuff and
the like and howto setup a test for that issue.
Poor me - I figured out the solution by torturing our app

I did not dig too deep to find out what exactly goes wrong in the old
statement used to create the new request instance, but I suppose
somehow not all specifications (interfaces) of the original request

fix in zope/publisher/http.py that circumvents the issue.
I don't know whether this is already fixed in the trunk or the fix
appeals to the devs with check-in permissions, but maybe someone
wants to look at it and check it in (or comes up with a better/more
