Because if there's two things in the world I don't care about it's wine
and the nvidia driver. So I won't spend any of my free time trying to
unbreak them when I've got more important things to do.
Ok, you are more important things to do but this bug concern your package. Like i said (and others persons too), this bug is present in Testing so if it's not resolved, there will be a important/critical bug in the future Stable. More people install the nvidia driver to play with wine or to use 3D apps... If this bug persist in Wheezy, it will be apocalytic. :p
