We don't normally want software in Fedora to annoy us with license dialogs. In particular not software that is installed by default. And this is really just a GPL program. We have thousands of those, and none of them sees the need to display disclaimers at startup, except for xsane...
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I've contacted upstream about it.
I somehow doubt thats going to help...after all, they put that dialog in in the first place.
I don't know, Oliver is easy to work with. Besides, it's the courteous thing to do -- we can always patch the Fedora packages to skip this dialog, if all else fails.
Fixed (patched away) in xsane-0.996-9.fc12
