#192 global name 'GroupSpace_sendMailPermission' is not defined

[Anonymous]

I am running python 2.4.1, zope 2.8.3, plone 2.1, gruf
3.5, ldapuserfolder 2.6, and grufspaces 0.6 on FC4. I
have set up a group of users from ldapusersfolder. I
created a grufspace folder and gave the group the
GroupMember role and added myself as GroupLeader. When
I click on the email tab and try to send a message to
the whole group I get the following message:
NameError
global name 'GroupSpace_sendMailPermission' is not defined

Here is the traceback:

What can I do to fix this?
