DCE/RPC is its own beast and may not fit nicely into the FT_GUID type. 
However, I'm not having any luck even starting to hack some DCE/RPC support in.
In the case statement mentioned above, I added

entry_str = "DCE/RPC";

(just for debugging)
And now shortly after returning from the DecodeAsDialog::entryString function
(where the case statement resides), Wireshark crashes (seemingly within Qt with
the selector_combo_box_->addItem() call that contains the entryString call.

I don't see much "obvious" setup for the other field types where FT_GUID isn't
setting up something that causes the addItem() call to fail.
Anyone have pointers?
