Change of Ownership Causes Nautilus to crash how can I change it back?

Question

Installing Solr I change the ownership of a folder called solr ... usr/share/solr-4.5.1/example/solr/ to tomcat7 but now when I try to change it back nautilus keeps switching off I have changed the owner back to ed, but it still is doing it in nautilus.

The original owner was Me to start with: What have I done, Why does nautilus keep crashing when I look at the permissions on this folder and how can I fix it?

Answer 1

The reason for the crash is probably a bug. You should report it. If you want to change ownership you can use:

sudo chown -R someuser:somegroup /usr/share/solr-4.5.1/example/solr/

Be careful that you don't mess up something else.

What have I done

You can't change ownership of files that are not longer yours, that's most likely the cause why Nautilus crash.
