I see this is #692979 in libimager-qrcode-perl.

I think libimager-qrcode-perl is the only package affected. The
only other reverse dependency of libimager-perl, libmojomojo-perl,
is arch:all.  Also, codesearch.debian.net doesn't give other hits for
PERL_INITIALIZE_IMAGER_CALLBACKS, which is where the error is coming from.

As libimager-qrcode-perl wasn't included in the last release (squeeze),
I'm not sure about the severity of #693002. I'm marking it as present
in the wheezy version, though.

If the Breaks line is indeed necessary for wheezy, I suppose it must go
in via tpu as sid has a newer upstream version.

The long-term way to fix this IMO would be very much like what we did
with libdbi-perl, which Provides: perl-dbdabi-94 and offers an interface
for packages to depend on that in a binNMU-safe way. That's #693003 and
post-wheezy material, I guess.

FWIW, the thing to look for is IMAGER_API_VERSION in imexttypes.h.
