** Description changed:

+ SRU INFORMATION:
+ Impact: Produces empty ddebs and broken debug links on packages which call dh_strip on a package more than once, when being built on Soyuz (not locally).
+ Patch: http://bazaar.launchpad.net/~ubuntu-core-dev/pkg-create-dbgsym/ubuntu/revision/180
+ Test case: http://bazaar.launchpad.net/~ubuntu-core-dev/pkg-create-dbgsym/ubuntu/revision/176
+ Regression potential: p-c-d has quite an extensive test suite which cover a lot of different build systems, debhelper compat levels, etc. Almost all bug reports get a test written first to ensure that it reproduces the bug and the patch fixes it. However, being a toolchain package it can potentially cause all further builds to be broken completely (which is very very unlikely, though); a more realistic regression potential is that this now causes debug packages to stop being built because the check for "has debug symbols" is imprecise.
+ 
  Update: Probably affects all packages which happen to run dh_strip twice
  on the same binary package.
  
  Binary package hint: xserver-xorg-core-dbg
  
  After upgrading to Lucid, I get the following error when trying
  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.
