Affects: nautilus (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I have problems copy/pasting files with Nautilus. sometimes it works,
but often it doesn't. It's easily reproducible though, in that that the
files that it refuses to paste, will never work.

For example I tried (as root) to copy/paste the file
/usr/share/icons/hicolor/48x48/apps/gnome-main-menu.png and it failed:
it copied it, but when I selected "Paste", nothing happened at all.

I tried as a simple user too, and same problem... some files can be
copied, some can't.

It works fine with Dapper Flight 3, the problem appeared after I updated
it.

I can't see any error messages when starting Nautilus from a terminal,
so I have no clue what's wrong.
