Looks like a Linux issue running TrueType fonts. Can you confirm the OS?

Also, we may get more information if the user runs with -Dsun.java2d.debugfonts=true.

[jim618]

I have added in some NPE protection for when the title font is set. If it fails the title font will probably end up small and plain but it should be readable. MBHD should continue rather than having a fatal Error Report.

Awaiting review and closing

[gary-rowe]

Verified working (code review).

Closing.
