The bug you encountered is sufficiently an "edge case" that it has not
gotten any attention from the people who could fix it.  Agitating for it
on the list is likely to be less productive than contributing:

  - Write one or more unit tests which demonstrates the failure (e.g.,
    they fail  with the current implementation).

  - Implement the fix, such that the new tests pass without causing any
    others to fail.

  - Submit the patch, including both the test and the patched
    implementation, as an attachment to the collector issue Andreas
    pointed to:  http://www.zope.org/Collectors/Zope/889

Such bug reports get quicker attention, because:

  - they demand less effort from the person with commit access to
    understand the problem (even without the fix, writing the test case
    would be valuable here).

  - they show that the bug matters enough to somebody to have invested
    the effort.

I have checked in a number of patches from Dieter in this way, which
means that Dieter is contributing to the "core" Zope code, even without
checkin access (which Dieter doesn't want to obtain).

Tres.
