Incorrectly claims that mainline kernel is running

[Nikolaus Rath]

I'm trying to report a bug against an Ubuntu kernel, but apport won't let me do it and keeps claiming that I'm running a mainline kernel. I have indeed *installed* a mainline kernel to test if the problem exists there as well, but I'm definitely not running it at the moment.
