I've found that this bug has regressed and returned on the production version of Trusty Tahr. All three of my rigs (two upgraded and one fresh install) are affected.
The bug affects nm-applet and nautilus-dropbox for me. For nm-applet, the fix involves editing /etc/xdg/autostart/nm- applet.desktop and changing exec=nm-applet to exec=dbus-launch nm-applet as per suggestion in http://askubuntu.com/questions/449658 /networkmanager-tray-nm-applet-is-gone-after-upgrade-to-14-04-trusty For dropbox, I taken what was mentioned in the article and changed the dropbox entry in Settings Manager -> Session and Startup -> Application Autostart -> Dropbox from Command: dropbox start -i to Command: dbus-launch dropbox start -i It appears that with 14.04, dbus-aware programs must be started with dbus-launch instead of directly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1271138 Title: Several icons stopped showing since updating to Trusty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-applet/+bug/1271138/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
