BTW, zsync daily build on 11/06, iso booted to same symptoms. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1366351 Title: compiz crashed with SIGSEGV in g_closure_invoke() if unity-settings- daemon goes away To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1366351/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
