The bug has been fixed in the newer nvidia graphics drivers (304 and 311) but it is still not fixed in the 173 package:
Loading new nvidia-173-173.14.39 DKMS files...
First Installation: checking all kernels...
Building only for 3.16.0-39-generic
Building for architecture x86_64

Error! Bad return status for module build on kernel: 3.16.0-39-generic (x86_64)

update-initramfs: Generating /boot/initrd.img-3.16.0-39-generic
This driver is needed for even older hardware (e.g. NV17GL) that is not supported by the 'legacy' 304 driver.
