Package: python-testtools
Version: 1.8.0-4
Severity: important
Trying to import the Twisted-related test machinery fails:
~$ python -c "import testtools.deferredruntest"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/testtools/deferredruntest.py", line
31, in <module>
from twisted.trial.unittest import _LogObserver
ImportError: cannot import name _LogObserver
This breaks any existing consumer of the above module.
The issue has been fixed upstream, but it affects the current version
in Debian.
A backport for the upstream fix is trivial and would look like:
