Hi Lennart,

As this is a serious regression introduced in your latest upload which makes
the package uninstallable on all architectures other than amd64, I've taken
the liberty of preparing an NMU for this issue.  The short diff to the
Debian packaging is attached.

I'm not sure how this regression happened, since the debian/rules handling
of the updates seems to be correct, but please take care to correct this in
your local environment before the next upload.

Changelog entry for the NMU is:

  * Non-maintainer upload.
  * Fix maintainer scripts to not hard-code the library path for one
specific architecture into the alternatives handling on all architectures.
Closes: #733568.

I will be uploading the NMU directly to unstable shortly, and have also
committed the change to the collab-maint repo.

Thanks for considering the patch.

Dear Maintainer,

upgrading or installing the package is impossible on i386 because 
x86_64 is hardcoded in the postinst script:
