I can confirm this bug using plain DevIL, no Ogre3d. Apparently the bug has been fixed upstream the 24th of april 2006 (see bug report on sourceforge.net [link in above post]).
According to http://openil.sourceforge.net/ DevIL 1.6.8 RC2 has been release 1st of September 2006 (so it doesn't seem dead to me). But apparently the new upstream version hasn't made it in a package yet. -- [Dapper] libdevil fails to load valid png's on AMD64 https://launchpad.net/bugs/34239 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
