<BUG> Courtesy key signatures at end of a line - next line displays all the naturals in the key signature

Musescore 0.9.6.2 stable, Ubuntu

Create a new score. Change the key signature in the first bar of the 2nd line of music. A courtesy key signature will be created at the end of the first line but they key signature at the beginning of the 2nd line will show all the naturals as well as the key signature (wrong).

Thanks,
