Comment 18 for bug 298545

@Robert Hrovat :
I'm noticing the same behavior too , but in my built-in webcam [laptop]
Sometimes the cam doesnt work and sometimes on reboot , it does work... But it is a not a bug in cheese since even when i test the webcam in gstreamer-properties , it shows the same problem [as you mention above with emesene]

And I'm not sure where the exact problem is either. But I'v found this in the messages logs whenever the cam doesnt work:

laptop kernel: [ 33.341883] usb 1-8: USB disconnect, address 2
laptop kernel: [ 33.342067] gspca: disconnect complete

Seems it might be a linux problem hence i'v reported Bug #552384 , do mention on the bug if you notice any such messages in the logs[ /var/log/messages ]

I'm closing this bug as fixed in cheese
