Delete unsaved file, keep backup => DrRacket crashes on startup

[bennn]

I'm on the Racket v8.10 release.

I made a file, saved it, made some changes in DrRacket, deleted the file on the command line, and restarted DrRacket.

Crash:

Worst of all, when DrRacket reopened it had none of my tabs.

(Maybe that's my fault and I unchecked a box somewhere? Still if there's no tabs to restore then please ignore my backup file!)
