nvidia-glx-new package & compiz shadows

In nvidia-glx-new package in ubuntu hardy, compiz shows pink shadows.
The bug was reported here : http://bugs.opencompositing.org/show_bug.cgi?id=781

(Please see a screenshot in attachment)

There is a solution to the problem, just correct the symlink :
sudo ln -s /usr/lib/nvidia/libwfb.so.xserver-xorg-core /usr/lib/xorg/modules/libwfb.so

I did it, it works.
But after a new version of nvidia-glx-new this morning, I have the problem again, and I have to "relink" the file.

So I think there is a problem in nvidia-glx-new deb package. It should correct the link.
