That symbol says the user ran the 64-bit slice of the app. I can't really recommend allowing 64-bit apps to run under Leopard. Yes, the support was there, but the 64-bit environment wasn't really RFPT in Leopard. There were a lot of little to big problems back then that made it just not worth it.
You might want to ask the user if they could try running the app as a 32-bit app, which they can do by checking a box in the get info window in the Finder. And if that makes the app work, then I would recommend setting the minimum OS version per-architecture key in the app's Info.plist so that the 64-bit slice will only run in Snow Leopard.
