** Description changed:

  After installing the compiz package 1:0.9.7.8-0ubuntu1.1 from the
  precise-proposed repository gtk-window-decorator started crashing and
  leaving the windows without any decoration.  I reproduced the issue on
  several up-to-date Ubuntu 12.04 (Precise) 64bit installations.
  
  From the cherry-picked patches included in the mentioned proposed compiz
  package I identified the one for bug LP: #929989 as the cause of the
  crashes. Rebuilding the proposed package after dropping that patch makes
  the crashes go away.
  
  [Test Case]
  1. Open IntelliJ (a Java IDE) with a project.
  2. Hit Ctrl+N (or Navigate/Class... menu) and wait for the small popup to show up.
  3. Start typing and wait for class name suggestions to show up.
  4. Hit Esc to close the popup window.
  5. Observe that system-wide all window decorations are gone (window titlebars are missing, i.e. no close/maximize/minimize button). You may have to repeat step 2-4 a few times until the bug gets triggered.
  
  [Expected Result]
  Window decorations do not disappear after closing the popup with Esc.
+ 
+ [Regression Potential]
+ No direct regression potentials.

  The program 'gtk-window-decorator' received an X Window System error.
  This probably reflects a bug in the program.
  The error was 'BadWindow (invalid Window parameter)'.

-   (Note to programmers: normally, X errors are reported asynchronously;
-    that is, you will receive the error a while after causing it.
-    To debug your program, run it with the --sync command line
-    option to change this behavior. You can then get a meaningful
-    backtrace from your debugger if you break on the gdk_x_error() function.)
