It sounds like a bug with version of D your using.  I make heavy use of 
toStringz with a lua wrapper I have.  If you can debug your program, try 
doing something like this.

char* ptr = toStringz(path);
SDL_LoadBMP(ptr);

and inspect ptr before the call to SDL_LoadBMP.  I would also replace 
string with char[].  To be sure that string isn't really wchar[] or 
dchar[].  Although, I imagine the compiler would catch that.
