[Python-modules-team] Bug#834921: python-ws4py: FTBFS too much often (AssertionError:)

[Santiago Vila]

Package: src:python-ws4py
Version: 0.3.4-3
Severity: serious

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

   dh_testdir -i -O--buildsystem=pybuild

--------------------------------------------------------------------------------

Because this source package only generates "Arch: all" packages, this
is the same as a FTBFS bug in the usual sense, and the fact that I was
doing "dpkg-buildpackage -A" does not mean anything special.

I attach three different faild build logs.

Thanks.
