I'm encountering what's probably the same issue.

Description: Header files for Linux 4.1.0-0.bpo.2-amd64
This package provides the architecture-specific kernel header files for Linux
kernel 4.1.0-0.bpo.2-amd64, generally used for
building out-of-tree kernel modules. These files are going to be installed
into /usr/src/linux-headers-4.1.0-0.bpo.2-amd64, and
can be used for building modules that load into the kernel provided by the
linux-image-4.1.0-0.bpo.2-amd64 package.
