Eclipse device management: NullPointer Exception while selecting device

Question

I have installed Motorola iDEN sdk for j2me (midp2.0) on Windows 7 with Eclipse 3.5.

I go to

window->preference->java me->device management and click the tab manual install.

I get the error no Error Searching For Device(java.lang.nullpointerexception).

I have also installed motodev_sdk; it works fine.

Can anyone help describe this error, and how would I best remedy it?
