Comment # 7 on bug 1113162 from Stefan Dirsch

Hmm. I can't reproduce the issue. Nevertheless I believe it's triggered by
running the %triggers of nvidia-gfxG05-kmp-default when installing
kernel-default-devel. You can extract the %triggers script by running:

  rpm --triggers -q nvidia-gfxG05-kmp-default | tail -n +2 > triggers.sh

Then run it via

  sh ./triggers.sh

My guess is that figuring out the kernel version fails for some reason. Check
this

  make -sC /usr/src/linux-obj/x86_64/default kernelrelease

And attach the output. Maybe then I can figure out what's wrong ...
