Subject: libunistring0: soname change without package name change

Date: Fri, 27 May 2016 07:15:48 +0200

Package: libunistring0
Version: 0.9.6-1.1
Severity: serious

0.9.6-1.1 features a soname bump from libunistring.so.0 to
libunistring.so.2, without changing the package name and making a
library transition. This breaks all reverse dependencies, e.g.:

(sid)ametzler@argenau:~$ ldd /usr/lib/x86_64-linux-gnu/libguile-2.0.so \ |
  grep unis
        libunistring.so.0 => not found

I'm preparing an NMU to revert to 0.9.3 (so the version will end up
being 0.9.6+really0.9.3 since I need to re-upload an orig tarball).

Manuel, if you want to re-do the transition, you can simply use
version 0.9.6+really0.9.6, until 0.9.7 is released.

Regards,

Stephen

Oh dear, sorry for the mess :(

I can work on that if needed, but if you are ready please go ahead.

Yes, I'll look into it once the main problem is addressed.

Thanks, I've uploaded a fixed package. I'm attaching the diff (which
applies on 0.9.3-5.3) — I don't think there's any point in integrating
it for future uploads :-).
