Description of problem:
openbox gets installed on the Xfce spin because it provides "firstboot(windowmanager)" which is needed by firstboot. Two problems here:
1. For Xfce this should be provided by xfwm4. The provides already was in the package and worked fine, but I accidentally removed it during the upgrade to 4.7.4.
2. If this is not provided by any package, a random one gets pulled in. On the spin this currently is metacity, others reported openbox (see bug 750380 comment 5)
Version-Release number of selected component (if applicable):
xfwm4-4.8.1-5.fc16 has been submitted as an update for Fedora 16.
+1 NTH, obvious impact to xfce, no impact on anything else.
