[Zope] Transience Error

[Chris McDonouogh]

Jim,

Does line 681 in lib/python/Products/Transience.py look like this
        for k in list(data.keys(None, delete_end)):

... or does it look like this:
        for k in data.keys(None, delete_end)

If it's the latter, please redownload the package and reinstall it
(there was a recent bugfix to this part of the code).

Thanks!

- C
