Protocol error with clients binding a wl_data_device multiple times

[elinorbgr]

If a client binds a wl_data_device associated with a given seat more than one time, when a data source enters it, the client dies with the following protocol error from libwayland-client:

not a valid new object id (4278190080), message data_offer(n)

The clients do not crash when doing the same manipulation on weston.

I suspect wlroots is sending wl_data_device.data_offer to all the wl_data_devices using the same wl_data_offer object, while the data_offer message has a new_id argument, so the same data offer cannot be reused this way.

Ah well, I guess I didn't search well enough.
