Title:
  using module-udev-detect leaks memory

Status in pulseaudio package in Ubuntu:
  Fix Released
Status in udev package in Ubuntu:
  Invalid
Status in pulseaudio source package in Karmic:
  Fix Released
Status in udev source package in Karmic:

Status in pulseaudio package in Fedora:

Bug description:
  --- SRU report follows ---
  Impact: Users of Ubuntu 9.10 may experience a local denial of service condition where the PulseAudio daemon process(es) exhausts available memory. This is caused by the default-used module-udev-detect not properly freeing invalid udev contexts.

  Fixed in 10.04: addressed in the latest Lucid source upload that
  contains the upstream fix

  Minimal fix for 9.10:
  http://launchpadlibrarian.net/37963834/pulseaudio_0.9.19-0ubuntu4.1.debdiff

  TEST CASE: On some configurations, this symptom is immediately
  triggerable. On others, it requires that the user choose a non-stereo
  multichannel profile in System > Preferences > Sound > Hardware >
  Profile

  Regression potential: low -- the existing upstream fix has been well-
  tested in Daniel T Chen's PPA and only touches the relevant code in
  module-udev-detect. The existing workaround of using module-detect
  will not be affected.

  Binary package hint: pulseaudio

  Pulse audio routinely uses 2GB+ over the course of a few hours.

  Description:	Ubuntu karmic (development branch)
  Release:	9.10

  pulseaudio:
    Installed: 1:0.9.16~test6-3-g57e1-0ubuntu2
    Candidate: 1:0.9.16~test6-3-g57e1-0ubuntu2
    Version table:
   *** 1:0.9.16~test6-3-g57e1-0ubuntu2 0
          500 http://mirror.optus.net karmic/main Packages
          100 /var/lib/dpkg/status

  I expect pulseaudio to continue to use a couple MB of memory,
  certainly less then 2GB.

  After a few hours of listening to music and the odd youtube video
  pulseaudio ends up with 2GB+ of memory.
