Agree; when you have steam installed the gnome-software steam plugin is auto-enabled which tries to download icons for steam apps when idle. It just so happens some of the steam apps use JPEG-2000 encoding inside the ICNS wrapper. For instance, try this: $ wget https://steamcdn-a.akamaihd.net/steamcommunity/public/images/apps/219/18380bfdc004844c918de769de298bac5c21ca33.icns $ eog 18380bfdc004844c918de769de298bac5c21ca33.icns eog: jas_stream.c:1044: mem_write: Assertion `ret == cnt' failed.
