Yeah, when I take a screenshot of any window created by Sun's AWT, it is
saved as Screenshot-Mainclassname.png.  When I take a screenshot of a
pure GTK application, it is saved as Screenshot-Binaryname.png.  When I
take a screenshot of our AWT, it is saved as Screenshot-.png.  gtk_init
sets the wmclass property of every window it creates to argv[0] (unless
one overrides the value with gtk_window_set_wmclass).  The screenshot
mechanism puts that property's value in the filename.  We currently set
argv[0] to "" when calling gtk_init, which explains the weird screenshot
name.

Yes, that's right.
