assertion `G_IS_OBJECT (object)' failed

 Hello,

 I have found many traces of similar problems on your list, but I haven't
managed to solved mine (maybe it is not possible?).
 I'm running RedHat 7.3 (Valhalla) with old gnome. For some stupid reasons
(I blame myself) I decided to install gtk+2.4 onjm this system. And of
course all programs like Ximian Evolution, AbiWord, gnumeric do not work
anymore. Typical error message is:
> /usr/local/bin/AbiWord-2.2

(AbiWord-2.2:11198): GLib-GObject-CRITICAL **: file gobject.c: line 1561
(g_object_ref): assertion `G_IS_OBJECT (object)' failed

** (AbiWord-2.2:11198): CRITICAL **: file pango-engine.c: line 68
(_pango_engine_shape_shape): assertion `PANGO_IS_FONT (font)' failed

** ERROR **: file shape.c: line 75 (pango_shape): assertion failed:
(glyphs->num_glyphs > 0)
aborting...
Aborted

 Everything I have installed from sources. Even AbiWord 2.2 (after gtk
installation). I have followed the gtk installation procedure (pangoo,
atk, glib-2) are also installed. Any idea what to do without upgrading the
whole system to some fedora?

  Best regards, Mariusz
