I contacted upstream, providing link to this bug and to the Debian policy "8.1 Run-time shared libraries" (http://www.debian.org/doc/debian-policy/ch-sharedlibs.html#s-sharedlibs-runtime).
It seems reasonable to them to update the SONAME next time they are going to break ABI compatibility. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
