App crushed when set 'w' equal to -0.5 in Quaternions mode

Describe the Bug
A clear and concise description of what the bug is.
I add an GPS in Spot robot's middleExtension, and change rotation mode to Quaternions, once i set 'w' to any negative number and confirmed, the App crushed.

Steps to Reproduce

1. add a Spot Robot in an empty world
2. add a GPS node in Spot->middleExtesion (i'm sure other nodes such as imu and Gyro have the same problem)
3. change GPS's rotation mode to Quatersions, and make sure w, x, y, z is zero as default
4. set 'w' to any minus number, click anywhere else to confirm
5. app crush

Expected behavior
I know that setting ’w‘ to a minus number is an illegal and incrrect operation, however i suppose webots can prevent those bad operations.
