Comment 20 for bug 312396

would you please link me to an example test case?

My previous post is not acceptable?:

SSH to a remote system via terminal
touch newfile
chmod g+rw newfile
chown otheruser newfile
under the places menu, 'connect to server' via sftp and open the newfile in gedit

Notice that even though you have the right to modify because of group perms.. Gedit says no (before patch)
After patch Gedit allows you to save changes to the file.
