This problem appears to be caused by /dev/shm having the wrong permissions (which is also causing me a number of other problems). Running
$ sudo chmod 1777 /dev/shm and logging out and back in fixes the problem (until the next reboot). I am not sure why /dev/shm has the wrong permissions - /etc/init.d/mountdevsub.sh calls domount tmpfs shmfs /dev/shm tmpfs -onosuid,nodev$SHM_OPT This doesn't specify mode=1777, so I am not sure where this mode should be getting set (although other users confirm they do see the correct 1777 mode). -- gdu-notification-daemon crashed with SIGSEGV in gdu_pool_get_devices() https://bugs.launchpad.net/bugs/418300 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-disk-utility in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
