Kerbal Space Program

Problem: Assigning a joystick axis to any of the yaw, pitch, or roll analogs in the input settings for EVA will break movement if the axis is used. The kerbal will then be only restricted to moving in one direction regardless of the directional key pressed. This occurs both in flight and on the ground.

Setup:
1) Assign roll, pitch, or yaw analogs in EVA input settings to any joystick axis.
2) Do an EVA.
Ground test:
3) [Sanity check] Attempt to move kerbal with default keyboard keys. (Should work fine)
4) Move the joystick on one of the assigned axes. (Nothing happens)
5) Attempt to move kerbal with default keyboard keys again. (Kerbal's movement is no longer locked to camera's direction and will move forward on any movement key)
Flight test:
6) Return to the Space Center to fix controls.
7) Go back to kerbal in EVA.
8) Hack gravity.
9) Enable RCS Pack.
10) Move up into the air with EVA RCS keyboard controls.
11) Repeat ground test steps. (Yields same results)

Occurs on both Windows 8.1 and Linux (Fedora 21). No information on OSX.
Joystick: Logitech Extreme 3D Pro.
