[xubuntu-users] Webcam support

I recently upgraded all my machines to Xubuntu 12.10 and generally 
things have been excellent. I now need some help out of my ignorance.

describes exactly what I have; but cheese crashes.

My USB webcam (a cheapo €12 bought at Tesco 3 years ago) worked 
perfectly under regular Ubuntu up to 10.04 but hasn't worked since.
dmesg reports:

camorama and kamerka both show the image OK, if a little slow.
vlc v4l2:///dev/video0 shows the image OK.
GUVCview also works, but it says it can only get 1 frame per second :-)

cheese crashes instantly on launch.
Flash web chat apps all detect no camera.
https://www.mozilla.org/en-US/plugincheck/ confirms I have the latest
    version of the Flash plugin installed.
Skype config detects CIF Single Chip but shows no image.
Google Talk plugin detects "gspca main driver" but shows no image.
Empathy config goes to Languages, Printers, and Software Sources (!)
Pidgin doesn't appear to have a video option.

I'm happy to buy a new webcam if need be, but I'd want a copper-bottomed 
assurance that it will work in Xubuntu 12.10. I'm just curious to see if 
the existing one could be made to work in Skype and Flash.
