OS X close Oni window (but not quit) then open new file causes error

[familyfriendlymikey]

On OS X, If you close the Oni window (but don't quit it using CMD + Q or Oni > Exit) such that Oni is still running, and then go to Oni > New File (or Open File, or Open Folder), Oni will give this error:

A JavaScript error occurred in the main process

Uncaught Exception:
Error: Object has been destroyed
    at executeVimCommand (/Applications/Oni.app/Contents/Resources/app/lib/main/src/menu.js:19:54)
    at click (/Applications/Oni.app/Contents/Resources/app/lib/main/src/menu.js:67:21)

Tested on a Macbook Pro 2015 (12, 1)

I looked through issues for someone else mentioning this error, but I couldn't find anything, so I apologize if this is a duplicate.

This is a real problem, experienced the same thing the whole time I have been using Oni on-and-off for the last few months.

Ah yes, thanks for logging this. It's related to #484 - we're not handling the menu state properly once the BrowserWindow has closed. We're keeping a handle to the old / destroyed BrowserWindow which isn't going to work too well.
