Skype webcam problem (/usr/lib/libv4l/ solved)

If you have problems with the webcam in skype with Linux, you may have read that you need to run skype with:

    LD_PRELOAD=/usr/lib/libv4l/ skype

However, you may get the message:

    ERROR: object '/usr/lib/libv4l/' from LD_PRELOAD cannot be preloaded: ignored.

Then try running instead:

    LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/ skype

This is caused by the new Multiarch support in Debian.
