Q: When I try to build a completely standalone XUL app on OS X (10.4.8). took an directory created with xulrunner-bin --install-app and tried to copy (using rsync -rl) the XUL.framework directory into a Frameworks directory in the .app bundle and then deleting the XUL.framework directory from /Library/Frameworks, my running my app fails silently. It works fine when the XUL.framework is installed in /Library/Frameworks. Any suggestions? "
