Please describe your issue in as much detail as possible:

Steam segfaults when launch options is set to just %command% for non Steam games. This does not happen for Steam games.
Sometimes when testing environment variables, it's easier to leave %command% instead of deleting everything and then having to rewrite it.

Steps for reproducing this issue:

1. Add any program (for example glxgears) as a non Steam game.
2. Set launch options to simply %command%.
3. Click Play.
