In an attempt to revive this thread (since it broke printing for me 
too), it appears that if a NULL pointer is passed to:

RtlCreateUnicodeStringFromAsciiz(&pNameW,pName);

then it returns an empty string in pNameW.buffer, rather than NULL.

Since these conversion functions are apparently APIs in Win2000 and 
later, which I don't have, hopefully someone could add test cases to 
dlls/ntdll/test/rtlstr.c to test what that function should return when 
passed a null pointer?
