This is a bug [1] in a library called "Nevow" [2]. (This bug was
mentioned in the Tahoe-LAFS Weekly News issue 10 that just came out:
[3].)

Until there is a fixed version of Nevow available, I think the best
work-around for this bug is to edit your src/allmydata/_auto_deps.py
file [4] and change the line that says "zope.interface" to say instead
"zope.interface == 3.6.1".

(That's because this bug in Nevow is triggered by new behavior in the
latest version of another library named "zope.interface". By pinning
the version of zope.interface that Tahoe-LAFS uses to be v3.6.1—which
is the next-most-recent version—we can avoid the bug.)
