I confirm that the bug affects nemo, too -- so presumably the root cause is not in nautilus. I am hit by the bug right after upgrading to 14.04 from 13.10.
I can reproduce the error with the following scenario: start nemo press shift-ctrl-n to create a folder. A new folder with 'Untitled Folder' created, the name is selected. press shift-ctrl again. The order is important -- shift before, ctrl after. The selection goes away, and now the folder 'Untitled Folder' itself is selected. after that, you cannot cut or copy -- neither with kbd shortcut, neither with menu items. As nemo visually gives feedback upon cutting a file, I can see that the cut action is not performed. I hope this helps. nemo 2.0.8 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1322925 Title: Copy, paste stops working randomly in Ubuntu 14.04 nautilus Status in nautilus package in Ubuntu: Confirmed Bug description: The title says it.
