Icedove 2.0.0.0-3 badly broken

["Edward C. Jones" <edcjones@comcast.net>]

I have a PC with an AMD Athlon64 3500+ chip. I have up-to-date Debian 
unstable, i386 port, on the system. Yesterday synaptic installed a new 
version of icedove: 2.0.0.0-3. This version was badly broken: I couldn't 
even press the buttons on the GUI. I replaced the broken version with 
1.5.0.10.dfsg1-3 which works fine.

The package documentation at debian.org says:

  Package: icedove (2.0.0.0-3, 2.0.0.0-2, 2.0.0.0-1, 1.5.0.10.dfsg1-3)

  Versions: 2.0.0.0-2 [alpha, hppa, ia64], 1.5.0.10.dfsg1-3 [arm, i386,
  kfreebsd-i386, m68k, mips, mipsel, sparc], 2.0.0.0-1 [powerpc],
  2.0.0.0-3 [amd64, s390]

Was there some confusion somewhere that led to the wrong version being 
installed?
