Unhelpful resolve failure

[jdm]

With my local servo clone, I had a import jsapi::jsuint in src/rust-mozjs/js.rs. This caused resolve3 to give up very ungracefully by just telling me that the import failed, as opposed to indicating which specific item failed.

Closing, assuming this is fixed. If it's not, please reopen or open a new bug with a repro case and a paste of the bad error message :-)
