Summary: Test testsub_vars() chokes on None values

Is this an actual issue? It looks so, but the title is misleading.

Anyway, my best guess with the limited information available is that the description field is NULL. We should probably catch this case in sub_vars() to be more robust.

Resolution: fixed
Status: assignedclosed

Ah, no, let's keep sub_vars() as requiring a string argument. The title is already guaranteed to be a string, so only the description could be NULL. Fixed in [11642].
