ID 534077 - The exportConfiguration function causes Katana to crash if querying for a value in a missing key

 
Customer reported version
Katana 4.5v5
 
Customer reported platform
CentOS 7
 
Steps to reproduce
 
1) In the Startup folder of a Katana Resources directory add the following code to the init.py file:
 

import os os.environ.pop('KATANA_PERSISTENT_IMAGES_PATH') print("Variable Cleared")

 
2) Launch Katana with the relevant Katana Resources directory added to the KATANA_RESOURCES environment variable.
 
3) In the Python tab run: Configuration.exportConfiguration()
 
Just to note: To repeat the above steps you must first reset the Environment variable KATANA_PERSISTENT_IMAGES_PATH to a viable directory.
 
Expected behaviour
Katana exports the Dictionary of Environment variables and prints it to the Python tab.
 
Actual behaviour
Katana crashes.
 
Workaround
Avoid clearing Environment variables during Startup.
