Encountered this crash while going through the Dev-Build-Headers smoke pass. It appears that attempting to connect to perforce is crashing the editor. I tried to connect it Subversion and that allows me to edit the values.
I tried this in Main and it is not happening. Also not happening on Mac
This is a Regression.
Result: The editor crashes
Expected: Able to fill in the options and connect to Perforce
