Problem in running dpkg --configure -a

Hi folks,

Debina (testing/unstable - 3.0)

# dselect update

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to 
correct the problem.

update available list script returned error exit status 1.
Press <enter> to continue.

Then I ran;
# dpkg --configure -a
Setting up foomatic-filters (3.0.0-20031207-1) ...
Configuration file `/etc/foomatic/filter.conf'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a new shell to examine the situation
 The default action is to keep your current version.
***  filter.conf  (Y/I/N/O/D/Z) [default=N] ?  D/Y/N and <Enter> (I tried all 
of them).  

It hanged here and I could not proceed further

Kindly advise how to fix the problem
