module-assistant tries and fails to install virtual package nvidia-kernel-source

[Diggory]

Binary package hint: module-assistant

When trying to build the nvidia kernel modules, m-a fails to get nvidia-kernel-source (since it is a virtual package). This is the error I get (on the command line, after closing m-a):
