analysis mode is broken when xboard is upgraded from 4.6.2-1 to 4.7.3-1

I initially reported this bug on Debian Bug Tracking System
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=743716 . But since there
was no response, I thought I'd ask for help here.

In the old version 4.6.2-1, when I do

rajulocal@hogwarts:~/chess$ xboard -fcp crafty
KamarajuKusumanchi_vs_paconov_2014_04_02.pgn

the game will start playing automatically. It can be stopped and moved to
the
beginning of the game by clicking on the "<<" button at the top right. Now
if I
press ctrl-A, the analyis mode will start and the analyzed moves will
appear in
a separate window. The analysis mode can also by started by Mode -> Analysis
Mode. Once the Analysis Mode starts, I can step through the program by
pressing
">" button at the top right.

In the new version 4.7.3-1, this behaviour is broken. After loading the game
and clicking on the "<<" button, if I press ctrl-A, nothing happens. The
Analysis
Mode under Mode menu is greyed out and not clickable. In both the cases
above,
I have crafty 23.4-6 installed.

rajulocal@hogwarts:~/chess$ dpkg -l crafty

My machine is a mixture of stable (Wheezy) and testing (Jessie).
