Kerbal Space Program

As soon as the "<" button is clicked for any axis under the input settings, the game crashes.

If I run from the terminal without steam, this is what it outputs.

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

Aborted (core dumped)

Both 32 and 64bit do the same thing here.

The lines of the player.log after the button is clicked.
