Getting Error when running Permissions Bukkit Command

I get a crash when I run the permissions bukkit command /permissions player setgroup

Error Found here:
http://pastebin.com/bg62R8GM

I thought it might be PermissionsBukkit plugin, but all the errors just have craftbukkit in them.

UPDATE: So when I manually place the group permissions in the config.yml file for PermissionsBukkit I got a screen full of:
http://pastebin.com/f4Y8Lyv9

" at com.platymuus.bukkit.permissions.PermissionsPlugin.calculateGroupPermissions(PermissionsPlugin.java:314)"
over and over and over for pages on end(above pastebin has clipped out about 200+ lines of it cause it just over stresses the point)

here is the code to add the user.

Code:

users:
    MachetePanda:
        groups:
        - user

Formatted incorrectly. It should look like this:

Code:

users:
  MachetePanda:
    groups:
    - user

 

Thats odd, I took it right from the permissionsbukkit project site. Thanks, I did what you said, but the errors are still happening, So it most be unrelated. I think Im going to post on the permissionsbukkit project as althought the errors are on the craftbukkit end it may help.

but related to craftbukkit. Anyone have any ideas?

UPDATE: Wanted to include the error with the new 1.3.1 -R2.0 build.

Now, here is the error when someone joins:
