error: Invalid serialized PackageId for key `package.dependencies`

[brocaar]

I'm getting the following error:

error: failed to parse lock file at: Cargo.lock

Caused by:
  invalid serialized PackageId for key `package.dependencies`

Probably this is caused by rust-lang/cargo#7579 (I found this reference in sfackler/cargo-tree#80, where the same issue was reported).

I'm also seeing the same issue with cargo-bitbake 0.3.12
