That's odd.  I usually use c_str().  c_str() adds a terminating \0 at
the end, but data() does not.  At least that's what Stroustrup says in
Section 20.3.7 of _The C++ Programming Language_.  Usually when I want
to print a char const *, I want that \0.

Also, I don't understand why you've had trouble with the intermediate
QByteArray.  It works fine for me.
