False "missing parameter" errors for gimbal mount

[durka]

Expected Behavior

I am calibrating a CubeBlack with ArduPilot 4.1 installed. MNTTYPE is set to zero, which causes all the other MNT* parameters to be hidden. I expect QGC to deal with this without throwing a fit. A warning would be acceptable, although still unwarranted, but a modal dialog is disruptive.

Current Behavior

A modal popup appears complaining about a number of missing MNT_* parameters, alarming users when in fact nothing is wrong. The full list is shown in the terminal:

FactPanelControllerLog: Missing parameter: "1:MNT_RC_IN_ROLL"
FactPanelControllerLog: Missing parameter: "1:MNT_RC_IN_PAN"
FactPanelControllerLog: Missing parameter: "1:MNT_RC_IN_TILT"

Steps to Reproduce:

Please provide an unambiguous set of steps to reproduce the current behavior

1. Flash ArduCopter 4.1.0
2. Set MNT_TYPE to zero
3. Reboot Pixhawk
4. Open QGroundControl
5. Navigate to Vehicle Setup

I guess, still no word on this problem?

Still occurs with latest Android QGC and ArduPlane on Cube Black.
