[maemo-developers] Running program icon does not show up

[From: Luarvique L. Luarvique]

I am having some problems getting icons to show up when running a
program. I have packaged and installed 3 different icons (26x26,
40x40, and 64x64) and I am running the gtk-update-icon-cache in the
postinst script. Here is what I get:

* The little icon in Application Manager does show up.
* The large icon in the start menu does show up.
* The small icon in the running-programs list at the left does not
show up. I am getting the default icon instead.
* The larger icon in the window list (the one that appears when you
click in the bottom-left corner of the screen) does not show up. I am
getting the default icon instead.

What am I doing wrong? Am I missing something?
