Public bug reported:
Impact
======
As part of jasper's removal from Debian, libicns lost its ability to convert
icons larger than 256x256 in Ubuntu 16.10. Ubuntu 16.04 LTS is not affected.
Test Case
=========
sudo apt install icnsutils
icns2png -x hdhr.icns
Should extract 5 icons without error
hdhr.icns is attached below and is from hdhomerun-config-gui
Regression Potential
====================
This patch was proposed to Debian but not accepted there yet.
Example Failure
===============
icns2png -x hdhr.icns
