Bug#37766: dpkg: dselect sigsegvs on window resize

[Inaky Perez Gonzalez <inaky@jovian.ucm.es>]

Package: dpkg
Version: 1.4.0.34

When running dselect on a xterm (tested with xterm and rxvt), once I
get the package listing window, if I resize the window [any window
manager], it'll redraw and then get the sigsegv. Can I provide any
other info?
