Your code looks fine. I'd check whether the icon is the right size for 
the OS (you don't say which). Windows XP expects 16x16 for the task bar 
& title bar corner icon, and 32x32 for the ALT-TAB task-list pane. Use 
IconBundle to get both.

There are some sample icons in bigdemo.rb sample - do these icon files 
work? If so, it may be some other problem with your .xpm file; you could 
try using PNG as a cross-platform alternative.
