ID 384664 - TimeOffset node crashes Nuke when the Properties Bin is set to automatically close using the hideControlPanel function.

Problem summary
It is possible to avoid opening a node automatically in the properties bin whenever a new node is created. This can be set at global level by hiding the control panel automatically after each node's creation, using a combination of the .hideControlPanel and addOnCreate functions.

An example of this would be the following:

def hideProperties():
    nuke.thisNode().showControlPanel()
    nuke.thisNode().hideControlPanel()
nuke.addOnCreate(hideProperties)

This option works great for all intended purposes, with the exception of the TimeOffset node. It has been found that having the above functions set will crash Nuke if any other nodes are added downstream of the TimeOffset node.

At this point in time, this appears to only occur with the TimeOffset node and no other node's from testing.

Customer reported version
nuke.11.3v2

Customer reported platform
windows10

Steps to reproduce

1) Open a new Nuke session 

2) Paste the following code into the Script Editor and run.

def hideProperties():
    nuke.thisNode().showControlPanel()
    nuke.thisNode().hideControlPanel()
nuke.addOnCreate(hideProperties)

3) Within the Node Graph, create a TimeOffset node.

4) With the TimeOffset node selected, create a Grade node.
Result: Nuke will crash

Workaround
Unknown. Avoid using the TimeOffset node if you are using the above or similar setup.

Alternatives can be either: 
- Changing the frame range in the Read node 
or 
- Using a Retime node to do the intended functionality.

Expected behaviour
When creating a TimeOffset node using a python function that stops the properties bin from opening on node creation, you should not get a crash when adding a node downstream to the TimeOffset node.

Actual behaviour
When creating a TimeOffset node using a python function that stops the properties bin from opening on node creation, you get a crash when adding a node downstream to the TimeOffset node.
