Description of Problem: An attempt to customize in Control Center any of "Appearance", "Focus behaviour" or "Matched windows" for Sawfish simply locks up control-center. Clicking on other entries at least produces something in a panel on the right beyond a gray background. Control Center at least can be killed and restarted after such lockup. How Reproducible: Reliably Steps to Reproduce: Just do it. Additional information: Starting "bare" sawfish and picking up Customize->Appearance from a sawfish menu has exactly the same effect only killing is harder. :-) One has to open a terminal and find out that 'gnomecc' is a faulty party.
I have no idea what changed but if yesterday I was not able to avoid this problem then today I cannot make it happen. There was no additional software installed and I tried different kernels. Sigh!
It's been changed to work better in Rawhide, too. There was some flakyness in the multi-capplet code.
