Sometimes getting the drive icon of a drive that isn't ready (e.g. dvd-rom) could lead to a crash. Since it can be very annoying I made this fix immediately.

Weirdly is that it happens only on the release build, so I didn't notice it before. It's weirder that now I catch the exception it seems no longer to happen at all. (as far I could try it, by opening/closing the game selector many times)

If the exception happens now the corresponding drive will just not have a icon.
