Comment 16 for bug 837196

No, it actually means there is nothing to fix I just have missed the updates to the bug.

It's invalid according to GNOME because there is a way to change the system hostname via System Information in the control panel:

As expressed above, there is also a way to change this in bluez itself, so there is effectively no bug in BlueZ -- as such I'll mark the Bluez task as Invalid (there is no bug there), and the gnome-bluetooth task as Won't Fix (we won't change how it is, and there is an alternative method recommended by GNOME already)
