Compiler Error: 'rustc' panicked at 'index out of bounds: the len is 1 but the index is 2'

Running clippy or build on the Vaultwarden code-base using `nightly` breaks.
It is broken since `nightly-2022-07-15` and still works on `nightly-2022-07-14`

Tried to run `cargo clean` before running this without luck.

If you need any more information, please let me know.
