potential kde-4.3.4 badness, X fails to start?

Just had 3 reports come in about X failing to start properly after up'ing to kde-4.3.4, https://bugzilla.redhat.com/show_bug.cgi?id=551310 "update to kde-4.3.4 - X startup fails, xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call" I'm very much hoping this is an exception and not the rule, esp after having kde-4.3.4 sit in testing repos for almost 2 weeks. Any ideas, help, debuggin, fortune telling, welcome. -- Rex
