When I launch Dungeon Defenders from Steam I get the usual "Preparing to Launch Dungeon Defenders" message, but the game never comes up. When I open the game through the terminal, I get the following error:

The game never loads, I don't even get to the splash screen.
I have a same (similar) issue on ArchLinux, the game crashes right after the splash screen. Using nVidia GT640M via Bumblebee (optirun steam), when running on integrated intel HD4000, the game, intro sequence etc run just fine. (But the game is unusable slow in the iGPU). So I guess it is something with the nvidia GPU, also missing 'linux32/libsteam.so: cannot open shared object file: No such file or directory' might not be an issue as it appears on intel gpu too (and game runs..)

I ran without sudo, got the same error exactly. It does run, the system monitor shows it up for about 15 seconds while it outputs the error message I posted, then crashes.
I was missing linux32/libsteam.so as well, so I copied it from somewhere else, I don't remember where off the top of my head. The error here didn't change, but it seemed to not have any problem with the libsteam.so file I gave it, so here is hoping that isn't an issue later.
