[c-nsp] 4GE-SFP-LC and CWDM SFP problem

We have installed in our network a 4GE-SFP-LC engine 3 linecard in a
12008 GSR. We wanted to use one CWDM-SFP-1470 with this inecard.
Unfortunately we were not able to do that:

GigabitEthernet3/0 is SFP security failure, line protocol is down
  Failure in Small Factor Pluggable Optics
  Hardware is GigMac 4 Port GigabitEthernet, address is 00b0.4a6d.9580
(bia 00b0.4a6d.9580)
  Description: SFP incompatibil
  MTU 1546 bytes, BW 1000000 Kbit, DLY 10 usec, rely 255/255, load 1/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Full Duplex, 1000Mbps, link type is autonegotiation, media type is CWDM-1610

router#sh inventory "slot 3"
NAME: "slot 3", DESCR: "4 port Edge Engine3  Gigabit Ethernet, HwVer#:
6.0,SwVer#: 12.0"
PID: 800-22811-06 rev A0 dev 0, VID: V00, SN: SAL094020L3

Does anybody have any idea why this is happening? I haven't been able
to find in the Cisco knowledgebase any of the error messages above.
And I couldn't find any document to say that CWDM optics would not
work with 4GE-SFP-LC.
