Title:
  library packages exist in a state of quantum superposition

Status in “apt” package in Ubuntu:
  New

Bug description:
  When I run 'sudo apt-get  dist-upgrade', I see this:

  The following NEW packages will be installed:
    libcrystalhd3 libfaac0 libva-glx1
  The following packages have been kept back:
    mythtv-common mythtv-frontend
  0 upgraded, 3 newly installed, 0 to remove and 2 not upgraded.
  Need to get 0 B/103 kB of archives.
  After this operation, 307 kB of additional disk space will be used.
  Do you want to continue [Y/n]? 

  If I install the packages and then run 'apt-get autoremove --purge', I
  see this:

  The following packages will be REMOVED:
    libcrystalhd3* libfaac0* libva-glx1*
  0 upgraded, 0 newly installed, 3 to remove and 2 not upgraded.
  After this operation, 307 kB disk space will be freed.
  Do you want to continue [Y/n]? 

  These libraries appear to be dependencies of the new libmyth-0.25-0
  library package.  mythtv is on hold here because there's no stable
  protocol, so client and server versions have to be kept in sync.  Not
  sure why apt is trying to install the dependencies anyway.
