gnome-terminal has scrolling problems when using screen

[Roland Dreier]

Binary package hint: gnome-terminal

I'm using feisty, and since the update to gnome-terminal 2.17.91, I see some very annoying problems when using screen with a status bar at the bottom (so that the scrolling area is not the full terminal display window). To reproduce this:

- start screen in a gnome-terminal window ("screen")
- after the screen splash screen, set up a status bar: hit CTRL-A :
  (control A followed by a colon) to get a screen command prompt,
  and then enter "hardstatus alwayslastline"

  this should produce an inverted line at the bottom of the screen.
- then run a shell command that will produce enough output to cause
  the screen to scroll, something like

    clear; for i in $(seq 100); do echo $i; done

On my system, this causes the gnome-terminal window to go completely blank, until I press a key, which causes the screen to refresh.

Changing the value 100 to 50 in the above command causes slightly different (still broken) behavior -- some of the intermediate output is displayed instead of a blank window, until I enter something, which causes the display to refresh to the correct state.
