QFont::exactMatch index out of bounds

      Application crashes in <QFontDef::exactMatch>

      It occurs due to index out of bounds when iterating over <families>.

      <families> has a count of 2 and  and <other.families> has a count of 1.

      There used to be a check in case the lists have a different size, but it was removed in: Change-Id: Id3c1a4e827756a4c928fed461a4aafa5a0f06633
