Quark 8 font list: PPC vs Intel

I have 2 copies of Quark 8, one running on a PowerPC G5 and the other on a Intel, when I run the below code:

tell application "QuarkXPress"
	set document_font_list to font list of document 1
end tell

The Intel returns the name of the fonts used and font Id in the document whereas the PowerPC returns the font id but leaves the font name blank.
Is anybody in the position to test this to see if they get the same results as me? I just want to be sure that this is down to the different levels of Mac I’m running it on rather than a preference.
