[Daniel Cantarín]

This bug was fixed in the package compiz - 1:0.9.8.2+bzr3377-0ubuntu1

---------------
compiz (1:0.9.8.2+bzr3377-0ubuntu1) quantal-proposed; urgency=low

  [ Sam Spilsbury ]
  * debian/python-compizconfig.install
    - Install compizconfig-python.pc
  * debian/patches/100_expo_layout.patch
    - re-add the expo layout that used to be in precise (LP: #1047067)
    - add some testcases

  [ Timo Jyrinki ]
  * New upstream snapshot.
    - Fix multiple window placement bugs (LP: #974242) (LP: #976032)
    - Don't waste CPU looping through and looking at all the windows if you're
      rendering an output that has no damage on it. (LP: #1014986)
    - Updated convert files to fix some typos in the key names. (LP: #1041631)
    - Fix crash when imgsvg is loaded, due to missing symbol
      (decor_apply_gravity from libdecoration). (LP: #956986)
    - Treat unresolved symbols at link time as an error, rather than letting
      them through and cause strange crashes later. (LP: #1043143)
    - Refactors a little bit of the upgrade code and gets it under test to
      prepare to fix (LP: #1042537)
    - Updated AUTHORS from the full bzr log, and re-sort the list.
      (LP: #1042095)
    - Fixes FTBFS for kde4-window-decorator (LP: #1041310)
    - Fix obvious omissions from the introduction of unminimize_*,
      which were causing the unminimize animation settings to be ignored
      (LP: #1040455)
    - resize plugin: don't crash if resize wasn't initiated externally
      (LP: #1045191)
    - Clean up capitalization (LP: #1045652)
    - Avoid division by zero, if plugins try to deform a window down to size
      zero. (LP: #1045235)
    - Make "Unredirect Fullscreen Windows" more reliable. This fixes the
      problem with unredirection failing to engage at all (LP: #1041066) when
      gtk-window-decorator creates offscreen windows that are stacked on top.
      This also fixes the problem with unredirect hiding all windows,
      because it thinks the desktop window should be stacked on top
      (LP: #980663).
    - Ensure unredirected windows don't stay unredirected if they're no longer
      on top. (LP: #1041047)
    - Fix launching terminal functionality and make show-hud default key
      visible. Update the defaults to org.compiz.integrated to reflect the
      actual gnome values pre-gnome-3. (LP: #1040081) (LP: #1046199)
      (LP: #1046190)
    - Fix show-hud, bump COMPIZ_GNOME_INTEGRATED_SETTINGS_LIST_SIZE.
      (LP: #1046212)
    - Fixed: Windows with an alpha-channel, like gnome-terminal, were not
      being considered as possibly covering fullscreen windows. But they most
      certainly can. This ensures such RGBA windows are visible if they're
      stacked above a fullscreen window. (LP: #1046661)
    - Remove ListToStringList (LP: #1046184)
    - Fix typo causing CMake Error (LP: #1045665)
    - Transitions gtk-window-decorator over to use GSettings. Add a testing
      framework for the options code. (LP: #1042323)
    - Also need kdeworkspace since kdecorationbridge.h is there
      (LP: #1046770)
    - Implements some cleanup that was suggested on the merge for the original
      port to gsettings. Other issues fixed as wel...

Hello Daniel, or anyone else affected,

Accepted compiz into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/compiz/1:0.9.7.8+bzr3121-0ubuntu1 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 change the bug tag from verification-needed to verification-done. If it does not, 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!

[Timo Jyrinki (timo-jyrinki)]

Not crashing anymore.

[Colin Watson (cjwatson)]

---------------
compiz (1:0.9.7.8+bzr3121-0ubuntu1) precise-proposed; urgency=low

  * New upstream stable branch snapshot.
    - Includes all the previous cherry-picked fixes
    - Fix crash when imgsvg is loaded, due to missing symbol
      (decor_apply_gravity from libdecoration). (LP: #956986)
    - Fix multiple window placement bugs (LP: #974242) (LP: #976032)
    - Fix window handle leak causing gradual degradation in desktop
      performance (LP: #1050610)
    - Some decoration pixmaps get leaked on window resize, due to race
      conditions between gtk-window-decorator and the decor plugin.
      (LP: #1057263)
    - Avoid a NULL dereference and give a useful error message instead.
      (LP: #944653)
    - Fix leakage of destroyed_pixmaps_table, containing pointers to freed
      decor_t's which could result in a freed GHashTable being passed into
      g_hash_table_remove and causing a crash. (LP: #1060171)
  * debian/patches/compiz-package-gles2.patch:
    - Drop the NEWS file, update decor.cpp part to build with new upstream
      code.
  * debian/patches/revert_fix_933776_955035.patch:
    - Cherry-pick the revert from upstream since the bug fix is not
      suitable for SRU as is
  * debian/patches/revert_fix_994841.patch:
    - Cherry-pick also this revert as non-SRU material, not relevant
      to users
  * debian/libdecoration0.symbols:
    - Update with latest symbols
