I installed the lasted SDK 1.4.2 RPM from Sun, rebooted and got the same problems as in http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=140081. I also have the updates mentioned in this bug installed since a day or two, but experienced no problems until I installed J2SDK today. The prelink solution solves (or works around?) the problem as well. Also, Firefox keeps crashing when I open a page with a java applet, but I guess this is because the plugin was compiled with an older version of gcc ?
