The new gtk2 icon code override the icon set by galeon with the mozilla icons.
To reproduce just try TestGtkEmbed and see that it use the mozilla icon.

proposed fix

The patch fix the problem by setting the default icon on Create, only when the
window type is not a child. So it will set it on the mozilla toplevel creation
but not on the gtkmozembed child creation.
I couldnt think to a cleaner fix ... hope it's ok.

Just noticed that the patch doesnt fix the problem entirely, will try to
investigate more.

Ok on some sites (, this bug page,, the
patch doesnt work because a toplevel (popup type) is created and immediately
destroyed ... Is this supposed to happen ?
Also I should have used mIsTopLevel instead of testing the type directly I guess.

The patch leave the popup toplevel out of our test. Appear to work this time.

The problem is more serious than I thought. Overriding the icon cause critical
g_object_unref warnings and crashes when closing windows. (Changing severity)

Maybe using the default icon is a bad idea.  Maybe we just need to set it for
toplevel windows every time.  That's reasonable.  This patch just sets the
default icon for the app once someone opens a toplevel window, which an app
might not want mozilla to do. :)

I was assuming we had two cases
1 Embedding apps. A toplevel window is never created (through nsWindow) and we
dont want the default icon to be set.
2 Mozilla. A toplevel window is created and we want to set the default icon.

So, I'm sure I'm missing something, I cant get what is "which an app
might not want mozilla to do" referred to.

Anyway, setting the icon every time sounds like a good solution to me. Thanks
for looking into this.

There's no way for the code to tell when Mozilla is embedded and when it isn't.
 And, frankly, I don't think that we should have to worry about it.  If we
create a toplevel window, we should be setting the icon, and we shouldn't use
the set_default at all.

set the icon only on toplevel creation (eWindowType_dialog and eWindowType_toplevel(

Note that these days another icon is set outside the widget implementation
using SetIcon. 
So default.xpm is not visible (at least in the cases I verified). 
I wonder if we still need to set the icon in nsWindow at all ...
