Hello hugo, or anyone else affected,

Accepted lsb into raring-proposed. The package will build now and be
available at http://launchpad.net/ubuntu/+source/lsb/4.0-0ubuntu27.1 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  Title: lsb_release crashed with IOError in getstatusoutput(): [Errno 10] No child processes
  UpgradeStatus: No upgrade log present (probably fresh install)
  UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo
  
  [Impact]
  SIGCHLD in lsb_release isn't handled correctly by Python causing the error code 10 IOError in some cases.  Upstream Python has a fixed subprocess module, so switching from commands (where it is not fix) to subprocess (where it is fixed) should do the trick.  Versions of lsb after precise are not affected because they use subprocess anyway, so this just backports that relatively mechanical change.
  
  [Test Case]
  Difficult to reproduce outside of teamviewer, but the following should work to verify that there is no regression: `lsb_release -a`
  
+ Also watch for no incidents involving the new package version at:
+ https://errors.ubuntu.com/problem/4eebfa6d3f91386f752207eeaf410b5a8ce81081
+ 
  [Regression Potential]
  If the patch to use subprocess is broken, then lsb_release may cease to work.
