Creating Group Programmatically with Reader Role

Question

I am working with SharePoint 2010. I am creating groups in my site through code. There is no issue in that. At the time of creation I provide "Reader" role for my groups. But when I browse the listing of site groups in my site the group shows it has "Limited Access" role. Could any one help me on this?

 public static SPGroup CreateGroup(SPWeb web1, string groupName)
{
  SPWeb web = web1.Site.RootWeb;

  SPUser user = web.CurrentUser;
  web.SiteGroups.Add(groupName, user, user, groupName);
  SPGroup oGroup = web.SiteGroups.TryGet(groupName);
  if (oGroup != null)
  {
    SPRoleDefinition role = web.RoleDefinitions.GetByType(SPRoleType.Contributor);
    SPRoleAssignment roleAssignment = new SPRoleAssignment(oGroup);
    roleAssignment.RoleDefinitionBindings.Add(role);
    web.RoleAssignments.Add(roleAssignment);
    web.Update(); 
    return oGroup;
  }
  else
    return null;
}

I don't see anything evidently wrong with that code.

Can you try "AllowingUnsafeUpdates" before doing the whole operation? Such as:

web.AllowUnsafeUpdates = true;

Also: were you able to debug into this piece of code? Does everything run as expected? Here are some things that you would want to check:

. The group does exist
. It finds the contributor role
. It's properly creating the RoleAssignment (instantiating it for the group, and adding the role)
. web.Update() succeeds (no exception thrown)

. At this point, try this: inspect the web object, get the group from SiteGroups and check if the RoleAssignment does exist at this stage.

Let's see what it comes out from the debugging session to further investigate.
