Flute Part Problem

I opened this score that I created in MuseScore 1.3 (which, granted, may be the problem) and cleaned up the parts. It all worked well except when I try to print the flute part. I get a message that says "PCL XL error". Then underneath it says "Subsystem: TEXT, Error: IllegalFontData, Operator: Text, Position: 11119". All the other parts print flawlessly, and I can't figure out anything different on the flute part than the others.

I am using the latest nightly R.8917b06 on a Windows XP computer. Thanks for any help.
