[Phoenix CVS, 2003-05-11]

This bug happened with a GTK2 build of Mozilla Firebird, but I do not believe it
is limited to that browser. On shutdown of Mozilla Firebird I saw this message:

(phoenix-bin:526): Gtk-WARNING **: A floating object was finalized. This means
that someone called g_object_unref() on an object that had only a floating
reference; the initial floating reference is not owned by anyone
and must be removed with gtk_object_sink() after a normal
reference is obtained with g_object_ref().

The places where g_object_unref is called are:

accessible/src/atk/nsAccessibleWrap.cpp:        g_object_unref(mMaiAtkObject);
accessible/src/atk/nsMaiHyperlink.cpp:        g_object_unref(mMaiAtkHyperlink);
widget/src/gtk2/mai/nsMaiAppRoot.cpp:    g_object_unref(toplevel->GetAtkObject()
);
widget/src/gtk2/mai/nsMaiCache.cpp:            g_object_unref(maiObj->GetAtkObje
ct());
widget/src/gtk2/mai/nsMaiCache.cpp:        g_object_unref(tmpMaiObj->GetAtkObjec
t());
widget/src/gtk2/mai/nsMaiInterfaceHypertext.cpp:        g_object_unref(G_OBJECT(
mMaiHyperlink->GetAtkHyperlink()));
widget/src/gtk2/mai/nsMaiInterfaceHypertext.cpp:        g_object_unref(G_OBJECT(
mMaiHyperlink->GetAtkHyperlink()));
widget/src/gtk2/mai/nsMaiTopLevel.cpp:                g_object_unref(oldMaiObj->
GetAtkObject());
widget/src/gtk2/mai/nsMaiTopLevel.cpp:                g_object_unref(newMaiObj->
GetAtkObject());
widget/src/gtk2/mai/nsMaiTopLevel.cpp:            g_object_unref(childMaiObject-
>GetAtkObject());
widget/src/gtk2/mai/nsMaiTopLevel.cpp:        g_object_unref(pMaiObject->GetAtkO
bject());
widget/src/gtk2/mai/nsMaiUtil.cpp:        g_object_unref(sRootAccessible->GetAtk
Object());
widget/src/gtk2/mai/nsMaiUtil.cpp:    g_object_unref(mai_top_level->GetAtkObject
());
widget/src/gtk2/nsWindow.cpp:        g_object_unref(mDrawingarea);
widget/src/gtk2/nsWindow.cpp:    g_object_unref(G_OBJECT(icon));
widget/src/gtk2/nsWindow.cpp:    g_object_unref(G_OBJECT(mIMContext));

[Christopher Blizzard (:blizzard)]

Yeah, I've seen this too.  I suspect it's a result of the theme checkin.

I don't remember seeing this particular Gtk warning.
Please REOPEN if it still occurs in a recent trunk build:
