Just in case this adds anything useful: I've seen this bug on both my desktop and laptop, both while about to launch a dist-upgrade from update-manager, exactly when the gksu prompt was supposed to display. In this incarnation, the bug makes compiz crash, attempting to restart it by switching to a VT and launching "DISPLAY=:0 unity --replace" briefly displays a full desktop which cannot be interacted with, and eventually crash again. The second time I got this, I went to a VT and did "killall gksu", and only then compiz was able to restart successfully.
So I guess this has to do with gksu's screen grab clashing with the recent stacking-order compiz fixes (never got this crash before Thursday). I should add that not every invocation of gksu causes this; a gksu dialogue correctly popped up while going through the apport bug reporting process. -- 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/856921 Title: compiz crashed with SIGSEGV in CompWindow::~CompWindow() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/856921/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
