Bug Description

Hello,

trunk r1708, archlinux

1) Go to "Tools -> Song Usage Tracking -> Extract Tracking Data"
2) Choose a directory to save the report
3) Try to extract the report.

It works, when I uncomment the order_by_ref argument. In the songusagedetailform

By the way, I am not sure if that is a dependency problem (which is why I attached the output of check_dependencies).

Just tried to reproduce this bug on trunk rev1710, but can't. Perhaps you didn't have any song usage data?

I am pretty sure that this is a dependency or version problem. Note, I had this traceback on arch.

Maybe it's the version of SQLAlchemy. Let me try installing 0.7.
