Please describe your issue in as much detail as possible:

I noticed the problem when trying to launch STAR WARS™: TIE Fighter Special Edition via Proton. There are three editions included with the game, and it's the Collector's CD-ROM version that fails to launch. In terminal, I get this output:

I found that the game launches correctly with %command%" (note the single trailing quotation mark).
