I'm seeing the following error in master (2a1082e3) when running tests:

I've chased it down to mediagoblin/submit/lib.py:208. Before this line, user is ok, but afterwards, it's detached from the SQLAlchemy session.

I've looked back through the version control history, and this error is occurring for me right back to when test_audio was added in c41705bf. That suggests that the error is related to an incompatible version of a dependency installed on my computer. I've attached the output of pip freeze.

This appears to not be related to #5323: Audio submission failing.

A user tried to upload a PDF file but it failed to process. I found the following in my celery logfile.
