It sounds like the pasteboard server on the machine has crashed or
otherwise gone away.
Your user with consistent problems—are they perturbing the pasteboard
in any way? (Running any custom copy-paste haxies? :) ) Does regular
copy-paste work for them in other apps like TextEdit?

Copy/paste simply stopped working in my application. It continued
to work everywhere else. Relaunching my application did not solve
the problem. Drag and drop also stopped working. Copy/paste
returned no error to the console but dragging produced a
"CoreDragCreate error: -4960"
After some extensive research on Google and the List archives, I
was unable to find a solution that did not require a reboot. One
potential issue was launching the app from the terminal during an
ssh session. I'm definitely not doing that. Another google result
suggested problems with launch services.
I was able to do some debugging before restarting my application.
It seems that calling [NSPasteboard generalPasteboard] returns nil.
It's like my application does not have access to the pasteboard
services.
Restarting solves the problem. On the one hand, I want to offer
this up to Fluke, Chance's ugly and less appreciated stepbrother.
Reboot and you're good to go. On the other hand, I have a single
user who is reporting this as a consistent problem. She reboots and
a few minutes later my app loses pasteboard functionality. Other
applications on the system don't seem to be affected, save one
which I won't mention.
