Some python programs don't call gtk.events_pending() often enough, or at
all, to redraw their display while processing. Anything with a
(working) progress bar would be calling events_pending() fairly often,
though. You'll see the "blank window" problems on programs that provide
no, or very little, visual feedback for operation's that take a long
time. It is generally a trivial problem to fix, though.

Squeaky wheel... File a bug report on the program and explain what it
is doing and precisely when. (i.e. rhn-applet-gui doesn't redraw window
contents while a "check for updates" is in progress.)
