I can easily reproduce this in piuparts.

Please fix this for jessie, the fix should be rather trivial.

In postinst configure, you most probably want to do this:

dpkg-divert --remove --package cyrus-sasl2-heimdal-dbg --divert
/usr/lib/debug/usr/lib/sasl2/libgssapiv2.so.2.0.22.mit --rename
/usr/lib/debug/usr/lib/sasl2/libgssapiv2.so.2.0.22

(based on the preinst script in lenny, the postrm script seems wrong as
it is missing the --divert option).
