Furthermore, this workaround :

> Analysis -> Decode As ->
> Choose [Decode]
> Select <MPLS> Tab,
> Choose <Data after label 146432==Ethernet PW (noCW) 

ONLY work on Wireshark version 1.6.7.

In version 1.7.1, the <MPLS> Tab is MISSING, only the <LINK> Tab is available.
So, this workaround is broken in version 1.7.1
