Description

As described in https://lists.apache.org/thread/xkrhgfpk9sr1mj74d4chz3r5yp3szt6c,

https://github.com/apache/arrow/commit/ef0feb2c9c959681d8a105cbadc1ae6580789e69

Caused some files written prior to 3.0.0 to be unreadable. Given that the patch was small, this will hopefully not be too difficult to fix
