Linux crash on content close

[realnc]

When closing content, I get a segfault.

The backtrace doesn't seem very helpful though. It doesn't contain anything from bsnes itself, only from RetroArch:

Thread 4 "retroarch-debug" received signal SIGSEGV, Segmentation fault.

Correction: There is not crash when exiting RA. It only crashes with "Close Content."
