Rather expensive thing - to lookup several directories, parse .desktop
files. Not sure it is good for the session startup (which should be as
fast as possible).

But if the window was not created ... Also, we completely forgotten one
aspect - when the application just starts, it can show its main window
much later (just measure the delay in galeon or evolution cases). But
gnome-startup cannot just stop and wait for this - just to get the icon.

Unfortunately in gnome-client API there is no function to point to this
.desktop file. So we are talking about API breakage again. Other than
this, it seems ok.

Some "default" icon probably can be still useful. Or - add the progress
bar to the splash window. Just to display the progress.

I don't really know (well, and probably I am not the man to ask - there
are smarter guys out here:). But anyway - ONE directory to look for
desktop files is definitely better than many.
