reassign 522360 agg 2.5+dfsg1-12 thanks This bug is not in the libagg-dev binary package. It is in the agg source package that libagg-dev is built from. Specifically, the source files in agg-2.5+dfsg1/examples/svg_test that are incorporated in exact-image. This bug will be marked as fixed when agg 1:2.4-r127+dfsg1 enters the debian archive.
The exact-image maintainer will have to copy source files from agg-2.4-r127+dfsg1/examples/svg_test into the exact-image codecs directory, making API changes as needed. Upstream changes made to the agg_svg files have been migrated to upstream agg so this should be easy. -- john
