Bug#29672: dpkg: dselect crashes when the xterm window is resized

[<alexander.schwartz@gmx.net>]

Package: dpkg
Version: 1.4.0.31

When you start dselect as root and then switch to the select mode, pass 
the help screen and then resize the xterm window (I use fvwm95 as window 
manager) is quits using the following error message:

  dselect: getch failed: Interrupted system call

As long as dselect is unable to adjust its data window, I would prefer
that it doesn't do anything.

Thanks, Alexander Schwartz (alexander.schwartz@gmx.net)
