when I close my laptop's lid to suspend and restart again then jitsi runs as usual exept the camera video which results in a black screen. I'd have to restart Jitsi to be able to do video conversations.
My system is an Acer Travelmate 5720 with Linux Mint 14 Nadja and an actual Jitsi Nighty (I kept up with the issue for some time and didn't have the time to report)

Nothing useful in the log. Probably there is an initialisation missing for the camera (???) I remember, the camera worked a while ago even after suspend/resume.
