[Bug 1154370] Re: [precise SRU] crash due to improper handling of "/" in GSettings

[Launchpad Bug Tracker]

This bug was fixed in the package glib2.0 - 2.32.4-0ubuntu1

---------------
glib2.0 (2.32.4-0ubuntu1) precise; urgency=low

  * New upstream release (LP: #1154657)
    + GSettings: Don't crash due to incorrect handling of "/" (LP: #1154370)
    + gio: Stop ignoring defaults.list wrongly (LP: #901171)
  * Update watch file to track 2.32 series for Precise
  * debian/control{,.in}: Require libelf-dev >= 0.8.12, per configure.ac
  * gnetworkmonitor_dont_leak_networks.patch: Drop, included in this release.
  * Install bash completion files into /etc/bash_completion.d; overriding an
    upstream change (not appropriate for Precise) to install into
    /usr/share/bash-completion/completions. This change also names the
    completion files correctly (after the commands they are completing for),
    so they will start working now.

Title:
  [precise SRU] crash due to improper handling of "/" in GSettings

Status in “glib2.0” package in Ubuntu:
  Fix Released

Bug description:
  GSettings in GLib 2.32.3 has a bug where the "changed" signal is
  emitted for child settings objects as if they were keys ending with
  "/".

  That was fixed upstream and merged into the glib-2-32 stable branch
  here:
  https://git.gnome.org/browse/glib/commit/?h=glib-2-32&id=e6f659a898595ba944bd02f0509b14694d1c26e7

  GLib 2.32.4 was since released and contains the fix.


  This fix is needed because there exists software (muffin) that
  contains code along these lines:

  
  void
  change_event_handler (GSettings *settings, const gchar *key, gpointer user_data)
  {
    ...
    g_settings_get_value (settings, key);
    ...
  }

  and it's invalid to pass a key containing "/" to
  g_settings_get_value() (causing crashes).

  This only happens when entire paths are reset (such as when running
  'dconf update').  That makes the issue relatively rare but it's
  affecting corporate deployments (Google, specifically).

  We should either do an SRU with just the patch linked to above to
  (ideally) QA and SRU the entire GLib 2.32.4 release to precise.
