[Pkg-octave-devel] Missing SOVERSION bump in graphicsmagick?

[Rafael Laboissiere <rafael@laboissiere.net>]

I am getting the following error message in a Debian unstable system:

error: default_formats: /usr/lib/i386-linux-gnu/octave/4.0.0/oct/i586-pc-linux-gnu/__magick_read__.oct: failed to load: libGraphicsMagick++-Q16.so.11: cannot open shared object file: No such file or directory

This is strange, because:

   $ apt-cache showpkg libgraphicsmagick++-q16-11 | grep '\(Reverse Dep\|octave\)'
   Reverse Depends:
     octave,libgraphicsmagick++-q16-11

and:

   $ dpkg -L libgraphicsmagick++-q16-11 | grep /usr/lib
   /usr/lib
   /usr/lib/libGraphicsMagick++-Q16.so.12.0.0
   /usr/lib/libGraphicsMagick++-Q16.so.12

It seems that a new upstream version was recently released:

   graphicsmagick (1.3.22-1) unstable; urgency=low

     * New upstream release.
     * Update libgraphicsmagick-q16-3 symbols file.
     * Update watch file.

in which there was a SOVERSION bump, but the package maintainer kept 
the package name "libgraphicsmagick++-q16-11", instead of creating a 
new "libgraphicsmagick++-q16-12" package.

Is my analysis correct?  Should I file a bug report against 
src:graphicsmagick?
