The fault seems to be that it tries to close joysticks that I don't have at
src/init.cpp:467.
This debug
for(int i=0;i<SDL_NumJoysticks();i++)
printf("%s\n", SDL_JoystickName(i));
prints this:
/dev/uhid0
/dev/uhid1
/dev/uhid2
I have logitech's keyboard, so is this SDL's bug?

Attached is a patch that fixed the abort trap for me.
