[Bug 79539] unplugging USB webcam causes khubd to go 100% until ekiga is closed

[Jerome Lacoste]

Public bug reported:

Binary package hint: ekiga

100% reproducible

1- plug webcam
2- start ekiga. image show on window
3- unplug webcam

results:
khubd goes 100% CPU

expected:
ekiga detects the removed camera and close the device, allowing the driver to correctly disconnect (and not trigger the CPU issue in khubd)

Reproduced using:
- ekiga 2.0.3-ubuntu3
- a USB webcam using the spca50x driver

According to the pilot author, ekiga should handle the problem better:

"le pilote préviend l'application qu'il n'y a plus de webcam en
renvoyant ENODEV c'est Ekiga qui doit en tenir compte et sortir sur une
erreur fatale aprés avoir fermé le device."

i.e. "the driver sends a ENODEV error and ekiga should take this into
account and close the device."

As for khubd taking 100% that also sounds like an issue, so I will open
another issue.

** Affects: ekiga (Ubuntu)
