"member of the wrong workspace" error

[fpoli]

In our project viperproject/prusti-dev cargo outdated fails with the following error.

error: package `/home/fpoli/src/prusti-dev/prusti-contracts/prusti-specs/Cargo.toml` is a member of the wrong workspace
expected: /home/fpoli/src/prusti-dev/Cargo.toml
actual:   /home/fpoli/src/prusti-dev/prusti-contracts/Cargo.toml

This error message looks related to rust-lang/cargo#5042, but in our case cargo build works fine. Is this something that can be fixed in cargo-outdated?
