gtk_widget_grab focus acts odd in GtkCList

[Kent Schumacher <kent structural-wood com>]

If I do a gtk_widget_grab_focus on a GtkCList, and then hit tab or an up or
down arrow, the first keypress seems to be lost.  The second and subsequent
keystrokes seem to work as expected.

I've attached a keypress signal handler to the clist and the first keypress 
appears to be eaten by something.

Does anyone have any suggestions on how to make this work?
