Hi, I had the same problem today and I could solve it by opening the compizconfig settings manager then choosing "effects" and selecting "window decoration". In "window decoration" window select "Enable Window Decoration" on the left hand side.
The compiz configuration in Debian has apparently a poor default configuration. Besides the missing window decoration, on my Debian Squeeze system essential things like "Resize Window" and "Move Window" (both in "Window Management") aren't enabled by default as well. Also "Gnone Compatibility" in the "General" section is disabled as well. The initial compiz configuration in Ubuntu is a good example of a sensible default configuration.
