Interestingly, xorg-server tries this:
dh_strip -pxserver-xorg-core --dbg-package=xserver-xorg-core-dbg
dh_strip -s --remaining-packages

Unfortunately that is wishful thinking, because dh_strip does not have
any --remaining-packages option.

I have tested that my fix works on the mesa packages. See the attachment
for details on what happens at which steps in the stripping processes.

** Description changed:

+ Update: Probably affects all packages which happen to run dh_strip twice
+ on the same binary package.

  to debug xorg:

  It worked just fine on 9.10.
  
  I've version 2:1.7.6-2ubuntu3 installed, on amd64.
  
  If you need more information, please let me know.
  
  Thanks,
