stock icons on Mac OS X 10.5

[Michael Tüxen <Michael Tuexen lurchi franken de>]

Dear all,

I just installed
- pkg-config-0.22.tar.gz
- gettext-0.17.tar.gz
- glib-2.14.4.tar.gz
- cairo-1.4.12.tar.gz
- atk-1.9.1.tar.bz2
- pango-1.18.0.tar.gz
via configure; make; sudo make install
and
gtk+-2.12.3.tar.gz
via
/configure --with-libpng --without-libjpeg --without-libtiff; make;  
sudo make install

to be able to do some work with wireshark on a fresh Mac OS X 10.5.1  
system.

Wireshark runs and shows all non-stock icons in the toolbar. The stock  
icons
are not shown and error messages are shown.

The problem can be reproduced by running
gtk+-2.12.3/tests/testtoolbar
and the following error messages show up:
(testtoolbar:72228): GdkPixbuf-CRITICAL **: gdk_pixbuf_new_from_file:  
assertion `filename != NULL' failed

(testtoolbar:72228): Gtk-WARNING **: Error loading theme icon 'gtk- 
new' for stock: Failed to load icon

(testtoolbar:72228): GLib-GObject-CRITICAL **: g_object_unref:  
assertion `G_IS_OBJECT (object)' failed

open' for stock: Failed to load icon

`pixbuf != NULL' failed

(testtoolbar:72228): GLib-GObject-CRITICAL **: g_object_ref: assertion  
`G_IS_OBJECT (object)' failed

... and a lot more of the same kind.

I think that the stock icons are .png files, so i checked that
/usr/local/lib/gtk-2.0/2.10.0/loaders contains libpixbufloader-png.la  
and libpixbufloader-png.so.

The wireshark specific icons are .xpm files, which work.

Does anyone have an idea what is going wrong?

Best regards
Michael
