Selecting "Cancel" in Resources dialog triggers a Seg fault with no error (Mac)

[vga-256]

I noticed that if I select File -> Resources, browse around for a folder without usable resources (e.g. no .html or .deck files or folders available, so the Open button is greyed out), if I click Cancel to exit the dialog, the program crashes with Segmentation Fault: 11. No error report is generated.

Running MacOS 10.14.6

Steps to replicate:

1. File -> Resources... -> Choose
2. Browse to a folder without any sub-folders so that the Open button is greyed out.
3. Click cancel. Program crashes. No error report or error trap.
   (if program is run from the Terminal on MacOS, it yields: Segmentation Fault: 11)
