Unhandled 404 error

I'm using download-npm-package to download dependencies of a project and I'm feeding this library invalid input at the moment (I believe). One results in an unhandled rejection and I don't see where the promise chain is broken:

(node:26572) UnhandledPromiseRejectionWarning: HTTPError: Response code 404 (Not Found)
    at stream.catch.then.data (P:\spodr\node_modules\get-npm-registry-package\node_modules\got\index.js:123:13)
    at <anonymous>
    at process._tickCallback (internal/process/next_tick.js:189:7)
(node:26572) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 5)

This happens, for example, when trying to retrieve css-frameworks@git+https://[email protected]/ben-eb/css-frameworks.git

The weird part is that this warning is logged, but my own catch handler is invoked.
