Bug#720385: minetest: game crashes with floating point exception

Wed Aug 21 22:51:01 UTC 2013

What does ldd have to say? I'd be interested in a "ldd minetest" run
against both versions, please. The thing is that the string "OpenGL
driver version is 1.2 or better." and its opposite friend are from
irrlicht, not from minetest. I suspect that this bug lays somewhere in
that library.

Thanks for your time,
Mt.
