Bug#702560:

[Milan Kostić]

 Well i reproduce this bug, it happens with some wireless devices
because joystick is enabled by default in game. Those wireless
adapters for example for mouses usualy create two devices and game
picked up that thinks it josytick but it is not...

 Long story short, bug can be in sdl, joydev or evdev who knows... but
it also can be not a bug if wireless jostick IS actually in use :).

 So i think just patching a game with joystick disabled by default
should be fine for most people.
