trace.c: ensure NULL is not passed to printf
GNU printf, and many others, will print the string "(null)" if a NULL
pointer is passed as the argument to a "%s" format specifier. Some
implementations (like on Solaris) do not detect a NULL pointer and will
produce a segfault in this case.
So, fix this by ensuring that pointer variables do not contain the value
NULL. Assign the string "(null)" to the variables are NULL.
