Hm. It's possible we fixed this, then. Feel free to mark it not reproducable
I followed the concrete steps above but the tests are failing instead of throwing Attribute error .
So, concrete steps are:
1) Download that course
2) Run a modified version of test_cross_modulestore_import_export.py that changes `COURSE_DATA_NAMES` and `TEST_DATA_DIR` to point to the downloaded course
3) Observe failure
Yes, this happened when I ran the CrossStoreXMLRoundtrip tests against the arbi/cs205/1T2014 course.
