The GDB retrace of Unity indicates a crash in the 3D video driver, probably due to poor power management capabilities in the driver itself. That, and the symptoms described in the Bug Description, are not related to unity-panel-service which is a separate process from unity.
There is still a crash in unity-panel-service to be investigated here. ** Tags added: unity-panel-service -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
