Dear Maintainer,

   * What led up to the situation?
        System update on debian/testing broke bumblebee.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        Installed linux-headers for the new kernel
   * What was the outcome of this action?
        Bumblebee worked again

Control: reassign -1 bbswitch-dkms
Control: tag -1 wontfix

bbswitch-dkms depends on dkms, which should pull in the correct
linux-headers package by itself (although dkms just recommends
linux-headers instead of depending on it), so this is not a bug in
either bumblebee or bbswitch. If you have configured apt to not
install recommended packages, either revert that, or take care of
installing the appropriate linux-headers package yourself.

Regards,
Vincent
