problem starting Gtk Applications

["Markus Jais" <mj gmx net>]

hi

when I start for example gedit I get this error.
$ gedit
gedit: relocation error: /usr/lib/libgtk-x11-2.0.so.0: undefined symbol:
gdk_threads_lock


with google I found a tip to upgrade to 2.4 but after upgrade I get the same
error. I also upgraded pango, atk, glib

/usr/lib/libgtk-x11-2.0.so.0
is a link to
/usr/local/lib/libgtk-x11-2.0.so.0
and this a link to

/usr/local/lib/libgtk-x11-2.0.so.0.400.0

and I also called ldconfig.

any ideas what when wrong here ?
