If you use a built in camera with your laptop (or a camera you cannot easily turn upside down), and realize that video is upside down in applications (Kopete, Pidgin, Skype, etc.), here is the fix:
apt-get update && apt-get install libv4l-0

Now start your application as following:
LIBV4LCONTROL_FLAGS=1 LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so kopete

or for 64bit systems:
LIBV4LCONTROL_FLAGS=1 LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so kopete

If FLAGS=1 it does not work, try using 2 and 3 instead. Having found your working start line, edit your application starters (e.g. in KDE menu) accordingly.
