Crash on close due to free of not allocated pointer

When closing VLC, I sometimes get a crash due to freeing an unallocated pointer:

vlc-osx-static(10517,0x7fffc13203c0) malloc: *** error for object 0x11a337e00: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
