This bug seems to be caused by incorrect detection of libpng16 in the
configure script. There is special handling for version 16 in the
detection code, but not in the part which adds the linker flags.
Removing the special code for libpng16 fixes the issue (and falls back
to -lpng which should work anyway).

I think that the crashes due to this bug are no longer happening due to
transitive dependencies on libpng16, but I have prepared an NMU with
the patch anyway since relying on these is horrible (and violates

I've uploaded the attached NMU to DELAYED/5. Please tell me if you want
me to cancel it.
