[Bug 29584] False reports of "Window not responding" error

[Douglas Green]

Public bug reported:

Affects: gnome-desktop (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Whenever I have made some edits to a document, then try to close the
application using the X in the upper right corner, it asks if I want to
close, cancel, or save.  Before I even get a chance to respond, within
1-2 seconds, a second dialog pops up saying:

--------------
Warning

The window "*Unsaved Document 1 - gedit" is not responding.

Forcing this application to quit will cause you to lose any unsaved
changes.

[Cancel] [Force Quit]
--------------

This has happened in different applications, gedit, gimp, etc.  The
warning is actually a false alarm because the window is actually
responding just fine.  I can cancel the warning and continue saving or
exiting as normal.

Note that this only happens for the X in the upper right corner of the
window, NOT for the Close or Quit options on the menu, which wait for me
to make a choice normally before exiting.

I am running Dapper Drake Flight 3 on AMD64 (plus a bunch of other
installed software and updates).
