[OpenAFS] Cannot create directory with Nautilus

[Jean-Marc Choulet]

Hello,

At work, I can create a directory in my $HOME with Nautilus (Debian 
Wheezy). My problem is with my personal computer (Ubuntu 12.04). I can't 
create a directory in  my $HOME on the same OpenAFS server. Menus are 
disabled. I must create directory with mkdir. And you, how do you do ?

Thanks,

Jean-Marc
