Comment 19 for bug 95854

Nope.
I just now did it again in nautilus/trusty (1:3.10.1-0ubuntu9.4). Even after "nautilus --quit" and "rm -rf ~/.config/nautilus" in case it was my old config.
Steps to reproduce:
1) create your crash test dummies:
$mkdir /tmp/test_real ; mkdir /tmp/test_real/foo ; mkdir /tmp/test_link ; ln -sT "/tmp/test_real/foo" /tmp/test_link/foo
2) open "/tmp/test_real" and "/tmp/test_link" in two tabs
3) copy- or move- drag "foo" from "/tmp/test_link/" into "/tmp/test_real/"
4) nautilus will ask non-indicative question (see above)
5) observe symlink "foo" (pointing at itself and marked as bad, of course) where the original "foo" once was.

The same happens while merging a nested directory (try with /foo/bar if you have doubts) - and then the user have absolutely no hints about what's going on, and data loss will happen.
