I experience this bug in Ubuntu 11.10. I dragged Evolution from the dash to the launcher. There is an empty space where I dropped Evolution. If I click there, I do get Evolution to start but there is no feedback whatsoever from the launcher.
Right-clicking does not produce the "Label Empty" item but instead produces a blank menu item. I'm going to attach a screenshot. While I was writing this comment parts of the GUI crashed, including compiz and unity-panel-service. They were automatically restarted. After restarting, the icon appears properly. ** Attachment added: "shows what right-clicking on the invisible icon does." https://bugs.launchpad.net/unity/+bug/772986/+attachment/2555062/+files/invisible_icon_bug.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772986 Title: Unity launcher single missing/invisible/blank icon To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/772986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
