I got the very same problem with compiz 0.5.
Removing the old compiz configuration solved it and logging out/in
solved it (run 'gconftool-2 --recursive-unset /apps/compiz').

But,

I still have no borders using : 
* compiz 0.5.0.dfsg-1
* xserver-xorg-core 2:1.3.0.0.dfsg-6
* Option "AddARGBGLXVisuals" "True"


Maybe this can be useful:

After I run 'compiz --replace', gtk-window-decorator takes nearly 100%
of my cpu resources...

$ compiz --replace &
$ top
PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

5926 steph     15   0 52096  12m 3932 S  2.0  0.8   0:00.65 compiz.real


Yet, borders work if I use compiz 0.2.2-1 (and reset compiz
configuration).


Hope it helps!

Don't hesitate to ask me if you need more information or tests (just
tell me what you need exactly because I don't know where to begin...)

Cheers,
