No, I think it's a real bug in ZEO, introduced by this checkin:

<http://cvs.zope.org/Zope/lib/python/ZEO/Attic/ClientCache.py.diff?r1=1.47.4.1&r2=1.47.4.2&only_with_tag=Zope-2_7-branch>

... but to my surprise, it's also fixed by the next checkin! which
appears to have been included in Zope 2.7.2:

<http://cvs.zope.org/Zope/lib/python/ZEO/Attic/ClientCache.py.diff?r1=1.47.4.2&r2=1.47.4.3&only_with_tag=Zope-2_7-branch>

So the easiest "fix" is probably to upgrade to Zope 2.7.2.

There really wouldn't have been any way to know this unless you had your
eyes peeled on the checkins list because the CHANGES.txt just says:

    - ZEO/ClientStorage: fixed check for temporary cache files (patch
       by Dieter Maurer)

... which is uselessly vague.

HTH,
