(copied from latest Debian bug message)
It appears that this issue is resolved simply by adjusting max_length of the group_settings_name GtkEntry widget. Attached is a patch which increases max_length from 16 to 32 characters. I do not know if this is only appropriate for recent Linux distributions (i.e. if kFreeBSD or other platforms using g-s-t have more conservative limits).
