I have installed current master on Ubuntu 14.04 with gstreamer0.10-ffmpeg from ppa:mc3man/trusty-media (as it's not included in Ubuntu 14.04 by default).

When I upload a video it fails after transcoding.

the file gets uploaded to srv/mediagoblin/user_dev/media/queue/media_entries/.../ where it actually is but afterwards it is requrested from: ​file:///mediagoblin/user_dev/media/queue/media_entries/.../

In /srv/mediagoblin/mediagoblin there is no user_dev but in /srv/mediagoblin.

the coreprivileges_users table consists of two foreign key columns: coreuser_id and coreprivilege_id. However, coreuser_id contains privilege ids and coreprivilege_id contains user ids! For example, running the query "DELETE FROM coreprivileges_users WHERE coreuser_id=3;" will delete all of the uploader privileges. Bad stuff.

Here is the offending code:

class PrivilegeUserAssociation(Base):

This table holds the many-to-many relationship between User and Privilege

tablename = 'coreprivileges_users'

privilege_id = Column(

'coreprivilege_id', Integer, ForeignKey(User.id), primary_key=True)

user_id = Column(

'coreuser_id', Integer, ForeignKey(Privilege.id), primary_key=True)

I don't understand what I'm doing, but here is a patch that adds aria-controls attribute that, according to a candidate recommendation (​http://www.w3.org/TR/wai-aria/states_and_properties#aria-controls), is supposed to tell some software that the down/up arrow icon controls the header drop-down.

At least it *hopefully* doesn't break anything and doesn't add any requirements for more attributes.
