StackOverflowException - VRTK.ObjectInteractEventHandler in Unity Build

See original GitHub issue

Environment

Source of VRTK: GitHub from 06 March 2017
Version of VRTK: GitHub 1dd32c6dea2762a0298f60a32ae52c3320df979f
Version of Unity3D: 5.6.0b10

Steps to reproduce

Not sure exactly - issue relates to grabbing and ObjectInteractEventHandler. It may possible be caused by recent changes to grab mechanics.
When the error occurred I was interacting with Unity UI on a canvas, the canvas is attached to a VRTK interactive object that is grabbed.
After reverting my version of VRTK to 87cc894c10e36faf22c15e8ab5f5cfa72ae768b1 the problem went away.

Expected behavior

Can move around the level and grab objects, no stack overflow error occurs.

Current behavior

After moving around the level and grabbing / interacting with objects and UI a few times, the stack overflow error occured. Seems to follow a pattern, in terms of the frequency for occurring. Once it happened the running game did not recover.
Error from Unity log:

StackOverflowException: The requested operation caused a stack overflow. at (wrapper delegate-invoke) VRTK.ObjectInteractEventHandler:invoke_void__this___object_ObjectInteractEventArgs (object,VRTK.ObjectInteractEventArgs) at (wrapper delegate-invoke) VRTK.ObjectInteractEventHandler:invoke_void__this___object_ObjectInteractEventArgs (object,VRTK.ObjectInteractEventArgs) at (wrapper delegate-invoke) VRTK.ObjectInteractEventHandler:invoke_void__this___object_ObjectInteractEventArgs (object,VRTK.ObjectInteractEventArgs) ...
