This issue has existed for some time, however in natty with Unity now being the default interface users are shown a warning that they lack 3D. This motivates them to try installing a binary driver via jockey. Especially if they're just testing to kick the tires, they may attempt to do so on media without sufficient space. Since for all NVIDIA owners the LiveCD boots with nouveau (currently defaulted to 2D-only), a lot of people will be encountering this particular bug work flow.
Because of this, I think the severity of this bug is critical.
