Using gnorpm operation find on file /usr/bin/gftp it correctly found the RPM. WHen the RPM was highlighted and the verify button clicked, a popup showed that gnorpm segfaulted.
This defect is considered MUST-FIX for Winston Release-Candidate #1
A little bit more information: I've traced this to dbiGet returning DB_NOTFOUND at rpmdb.c:1412, from verify_packages in gnorpm (verify.c:87).
I have a fix for this. Testing now.
