Comment (by rycee):

 Ok, gave bisect a try and it told me that the issue was fixed in commit
 [https://github.com/warner/tahoe-
 lafs/commit/095efbf7a5f8ee375a81136f87ba3943ec995fc6
 095efbf7a5f8ee375a81136f87ba3943ec995fc6]. This change seems to make Tahoe
 depend on pycryptopp version 0.5.20 or later on my machine, before this
 change it was satisfied with version 0.5.14 or later.

 On my Debian Squeeze installation, the python-pycryptopp package is of
 version 0.5.17-1+b1 satisfying the dependency before davidsarah's change
 but not after. Finding this out, I of course tried uninstalling the
 python-pycryptopp Debian package and rebuild a pristine Tahoe 1.8.2 source
 tree. The failing test now happily passes!
