From Bugzilla Helper: User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.6-3.1 i686) 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 How reproducible: Always Steps to Reproduce: 1. Upgrade from 7.1 2. Run Gnome 3. Nautilus select wizard will run but not work. Additional info:
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.
