Bug#1399: dselect error handling not consistent

[Marcus Brinkmann <Marcus.Brinkmann@ruhr-uni-bochum.de>]

Hello,

Report: 1399
Status: Open, should be easy to fix.
Analyse: dselect bails out if "Select" is choosen while db area locked.
Explanation:
 While dpkg database is locked, dselect can't operate cleanly.
 However, when choosing Configuration, Installation or Removal, it does not
 bail out back returns back to the main menu.
Strategy:
 Make dselect return to the main menu if Select is choosen while database is
 locked.

thanks,
Marcus
