      Description

      When parsing NMEA "full" log file with instance of QNmeaPositionInfoSource class timeout is notified whatever update interval is set.
      But when leaving only $GPGGA and $GPRMC lines in NMEA file everything works perfectly.

      Indeed, when there is $GPVTG NMEA messages in file there is problem with timeout event. $GPGSV - seems to not cause problems. I haven't tested other NMEA messages separately.

      See simple project attached. It writes to console coordinates of updated position every second (according to NMEA messages), but it get stuck with first $GPVTG message (updateTimeout() signal is emitted and parsing process stops)
