Comment 16 for bug 544994

If it was fixed in 0.12.8-0ubuntu2 it's now regressed in 0.12.8-0ubuntu3 on my fresh Lucid upgrade.

lsof snippet:
gvfs-gpho 6062 floid 13u CHR 189,146 0t0 2544556 /dev/bus/usb/002/019
...
rhythmbox 6244 floid 43u CHR 189,146 0t0 2544556 /dev/bus/usb/002/019

Rhythmbox gets hung up sleeping (Sl state) as soon as the camera is connected / if it is run with the camera connected.

This causes the ever-complained-of "Error mounting location: Error initializing camera: -60: Could not lock the device" from gphoto2 and its consumers. At some point I got a -1 error out of it as well.

Of course it's an unexpected race depending whether gphoto2/F-Spot/similar is run before Rhythmbox or not. But with Rhythmbox closed, the device actually works as a PTP camera in F-Spot, much to my relief, and it even gvfs mounts (so turns out I'm not affected by another bug I thought I was).
