isync: I also tried what you suggested and (from a clean start), the copy and paste works ok.
For me, this issue appears to happen randomly after a period of time and like everyone else, I'm extremely frustrated by this. Copy and paste is a fundamental part of a file explorer and for it to fail so badly in the default program and not be fixed for months is pathetic. Rant over, I've found that if nautilus is run from a terminal, after copy/paste fails, these errors appears in the window: (nautilus:18784): Gtk-WARNING **: Inserting action group 'ClipboardActions' into UI manager which already has a group with this name (nautilus:18784): Gtk-CRITICAL **: gtk_widget_get_clipboard: assertion 'gtk_widget_has_screen (widget)' failed (nautilus:18784): Gtk-CRITICAL **: gtk_clipboard_request_text: assertion 'clipboard != NULL' failed These errors appear over and over whenever a paste operation occurs (copy and cut don't seem to report anything). I don't know whether this helps fix the issue, but it should at least point towards the area. -- 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.
