chmod does not update server view

using chmod on a file or dir on a server does not update the server view, nor does it update the dialog box if called again.

steps to reproduce:
- in the ftp view, right-click on a file and select "chmod"
- change the permissions and press ok
- the permissions column is not updated and does not reflect the situation, if the chmod was successfull or not

even worse:
- after the above, click the same file again and bring up the chmod dialog - it will display the old settings, not the updated ones

temporary fix:
- press F5 after each chmod

Thanks.
