ID 516051 - Node Graph palette can stop working in projects containing Nodes with NaN positions

Follow

Problem summary
Node Graph palette can stop working in projects containing Nodes with NaN positions
 
Customer reported version
Mari 4.6v4
 
Customer reported platform
CentOS 7
 
Steps to reproduce
 
1) Download the attached project

2) Open the Node Graph palette

3) Switch to a different Object
 
Expected behaviour
The Node Graph should function as normal.
 
Actual behaviour
After switching the Objects, the Node Graph can no longer be used. Switching Objects back, or opening a different project in the same Mari session do not resolve the issue. 
 
Workaround
Restarting Mari will return the Node Graph to a usable state. However, opening the same project will still cause the issue to occur.
If you are experiencing this issue with a project, please contact Foundry Support (support@foundry.com).
