Shouldn't imagemagick have a better transition plan instead? The entire point 
of having libmagickcore-extra is to isolate packages from imagemagick's 
transitions -- requiring a versioned package to be listed in the build-depends 
means that it becomes ensnared in each and every transition even when it is 
not using any symbols from the libraries directly. All these packages need is 
a working convert(1) and all that requires is for the old provides to be 
removed and the new one introduced as per the discussion of virtual packages 
in build-dependencies in Policy.

We seem to go through this repeatedly with imagemagick transitions... it'd be 
great it we could avoid breaking rdeps :(
