Make a lua script that trys to load a non existing file, eg:

loadfile ( "/file" )
OR
dofile ( rb.current_path ( ) .. "randomfile" )

run it; A segmentation fault occurs. (At least in my sim)

I've tried to narrow it down, and it seems to be causes at line 557 of apps/plugins/lua/lauxlib.c
"const char *filename = lua_tostring(L, fnameindex) + 1"
==> if you take away the +1, it works, but I think that would change what its pointing too....

This task depends upon

That code isn't ours, so I think this should also get reported upstream.

edit:
This seems like it's a mistake in my code, I'll look into it
