Ok more than likely not a bug but a problem we are going to see in support. People who preform upgrades and use WindowMaker will run into difficulties trying to use their old config files, since some of WindowMaker files like Wprefs have moved from /usr/X11R6/lib/GNUstep/Apps/WPrefs.app to /usr/lib/GNUstep/Apps/WPrefs.app also since other functional changes here made here like the removal of the clip icon, and the functions droped into the applications menu.
Okay, the directory change will mess with us, I'll look at it. BUT, the removal of the clip icon will NOT hamper the installed base, as it is only taken out of the global defaults (and anyone with their own preferances, ie: anyone who is upgrading, has local defaults already)
Okay, I've looked at this, and this is just gonna break no matter what we do. the only fixes would be to either: A) Put a symlink in /usr/X11R6/lib (which is not what we want to do to keep this running, when can we trash it? - or - B) make the Window Maker rpm recursively walk the home directorys and 'fix' their config files, which is such the wrong thing I don't want to think about it. So we can't really fix this on upgrade, as the problem is in user config files. I assume the archetecture change will go in the changelog, so I'm gonna close this as 'WONTFIX'
