[PKG-Openstack-devel] Bug#848888: python-testtools: The testtools.deferredruntest module is not importable

[Free Ekanayaka]

Hello,

I've prepared a 1.8.0-4.1 NMU upload to fix this bug, you can find it in
the debian/bug-848888 branch of this repository:

git://anonscm.debian.org/collab-maint/deb-python-testtools.git

The relevant commit/diff is:

https://anonscm.debian.org/cgit/collab-maint/deb-python-testtools.git/commit/?h=debian/bug-848888&id=429fb32d6f81f62e900750c7354d311b5605db5e

If there are no objection I'll proceed with the upload (or lemme know if
you want to do it yourself).

Cheers,

Free
