I think that was because it was built with libMagick++4 whereas 14.04 and newer Ubuntu versions have libMagick++5. I am not sure why this matters (sounds to me like something may be improperly symlinked system-wise).
i would say that Debian has a pretty well established system to avoid breakage of applications due to library incompatibilities.
part of this scheme is to rename library packages (e.g. "libMagick++4" vs "libMagick++5") if and only if the two libraries are binary incompatible. usually this means that some previously exported symbols have vanished in the newer version.
a specific application might not use those symbols at all and would thus not be affected by the incompatibility. but using symlinks (system-wide!) is certainly the right approach to break your system, and thus should be avoided.
there are two solutions for this problem:
