Bug#609577: Entering directory without permission: no error message

[Jan Kolarik <kormoran@justmail.de>]

Hello,

sorry for missing information above (they were never requested from 
"reportbug" or i oversaw them).

Here they are resp. how to reproduce the problem:

- Set view mode to "Columns": Menue View / View Mode / Columns

- Enter a directory where you don't have any (or not enough?) permissions,
  e.g. /root (drwx------)

- Now there doesn't occure any hint about the missing
  permissions.
  An error message would only occure at the bottom of the window
  if you are in Icon or Detail view

- To the contrary the forbidden directory is opened as a new column

- All this makes the user think the directory is not forbidden
  but only empty
