[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I get the same message as above:
QLayout: Attempting to add QLayout "" to PhononWidget "", which already has a layout
QDBusObjectPath: invalid path ""
Strangely though, occasionally Videos will play in the information panel, but only about 1 in 10 attempts, and it seems purely random.

Is anything going to happen with this issue, sorry guys but it is frustrating
