mixxx crashes when trying to access rekordbox

[Yoren]

Bug encountered on
- OSX 10.15 or a macbook air (core i5, 8GB) (mixxx 2.3-beta-4274-g32bb2d05b9), and
- Raspbian 64 bit (Raspberry pi 4, 8GB) (mixxx 2.3-beta-4291-ga96d302ae3)

Steps to reproduce the problem:
- In library, click on Rekordbox. An arrow appears to expand
- Click arrow, the usb drive shows
- Click usb drive, Mixxx crashes (closes)

- The crash happens specifically with one of my sticks. Two other sticks work fine.
- Sticks are plugged directly into the machine (without usb hub)
- Files on the stick are readable when accessing them through the file browser

Expected behaviour:
- Show the contents of the recordbox library
- Gracefully handle exceptional cases (eg incompatible rekordbox version/corrupted data/permissions/whatever might be going wrong.) But do not crash

Information logs
- Rekordbox export db
- Backtrace generated on raspberry pi

I forgot to think about the obvious yesterday, but i just checked: and the usb stick doesn't work on pioneer cdjs anymore either. Maybe the file is corrupt?

It would still be great if mixxx could tell me that it can't read the drive instead of suddenly stopping.
