I think that is another instance of what #987575 is attempting to fix.

Do you have any other *-dkms packages installed? This sounds like some 
old module that is no longer compatible with the current kernels is 
attempted to be built and causes deletion of some files from the kernel 
headers.

You could install debsums and run 'debsums -c' to find modified or 
missing files and then reinstall the affected packages (after dropping 
cruft *-dkms).
