An anonymous user writes:

The application crashes after double-clicking a folder in the "Loading..." state. This doesn't always happen, but does frequently enough that it should be easy to reproduce. Found on Windows and Linux. Probably also occurs on macOS.

Steps to reproduce

1. Accept an invite to several folders (tested with 5 or more) from another machine
2. Download all folders at once into the same directory
3. Double-click the folders in the "Loading..." state until the crash occurs

What is the current behavior?

Crash with traceback:

Traceback (most recent call last):
 File "gridsync/gui/view.py", line 172, in on_double_click
KeyError: 'directory'

Possible fixes for suggested remediation

Silent error handling and GUI inaction will probably be sufficient.
