Description of problem:
When I upgraded from RedHat 7.1 to Roswell, the first time I ran the GNOME
desktop, a wizard popped up asking if I would like to use Nautilus as the
default desktop manager. I selected yes and hit Next. It asked for me to
hit Finish to make the change... I could click it but nothing would happen
(the button depressed and raised when I released).
The back button and the cancel button worked as expected.
It continues to show this
Steps to Reproduce:
1. Upgrade from 7.1
2. Run Gnome
3. Nautilus select wizard will run but not work.
I had the same problem after upgrading, but this seems to be related to the
presence of former .gnome* and .mc directories that confuse nautilus. In a first
attempt, I killed that pop-up window, and launched nautilus from the shell.
Later logins behaved normally. I removed former .gnome* and .mc directories from
my other accounts, and those behaved regularly at logging in for the first time.
This was just a bug in the wizard. The cool part was, every time you clicked
Finish you got another Nautilus added to your session. Which led to some
interesting effects. ;-)
It should be fixed in gnome-core from Rawhide.
