I would expect mysqldump to ignore the parameters that start with a whitespace. The argument list should be build like this:
  QStringList arguments;
  arguments << "--user=root";
  arguments << "--password=david123";
  arguments << "--host=localhost";
  arguments << "--result-file=/home/david/tmpDavid.sql";
_without_ an additional whitespace left of the "--". Your approach ends up with the command line

  mysqldump " --user=root" " --password=david123" ...

which might get misinterpreted by mysqldump.
