If this is now closed, please re-open. I have just experienced this bug (see attached) on a Dell 9150 running 64bit Ubuntu 12.04 as updated on 2012-05-16.
I was copying from an external 2Tb USB drive via USB2.0 to an internal 300Gb IDE drive. I had earlier done a multiple drag and drop copy, and the fileops window showed just what it should - multiple copies in progress. When that had finished, I did another D&D copy and the fileops window was blank as attached. Later still, I did another (two files selected) copy and that time got NO fileops window at all. All file copies seemed OK though. I have not yet rebooted, but expect I will see what earlier reporters saw, that is, that the error clears at least temporarily after a reboot. ** Attachment added: "BlankFileOps.png" https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/515435/+attachment/3149757/+files/BlankFileOps.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/515435 Title: File-operations window is emtpy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/515435/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
