unity-panel-service crashed with SIGSEGV in gdk_device_get_associated_device()

[Fabio Marconi]

Hello
I was watching a movie with totem, then I clicked the mail icon on notify area, but nothing worked, tried with BFB and the launcher but nothing again worked.
In tty i've seen totem running at > 60% and xorg 20% of cpu, I've killed totem, then immediatly apport start tracking this and xorg return at normal levels.
Not sure it is 100% an issue with 'unity-panel-service' or a problem with totem, because after killing it the system still working as expected.
Thanks
Fabio
