Thats the error from alerts but any of the fab tests that use the VirtualDjango facility have the same problem.
@Jbonnett: do you have the test case that was causing this and the command you were executing? I assume a straight fab test?
Yep. Its fab test on anything that using virtual django. Basically anything but the audio and video back ends. The only trick is to set up django 1.4 in your dev env. But that is as simple as checking it out and putting it in your python path.
All of Armstrong works with both Django 1.3.1 and 1.4.
