1626810 - Component manager fails while trying to load chrome.manifest in packaged builds

Status: NEW

(Core :: XPCOM, task, P3)

Description

[Andrew McCreight [:mccr8]]

I wrote a patch to assert in various places in the component manager if they fail, including the load that happens in nsComponentManagerImpl::ManifestContract(). If I push that to try, that assert fails, with the message:
XXXX Could not read chrome manifest 'file:///builds/worker/workspace/build/tests/bin/chrome.manifest'.

This doesn't happen locally. My guess is that in a package build we're still trying to load this manifest file, but it doesn't exist in a packaged build.

I guess this is actually happening inside some instance of XPCShell used for some server thing during a Mochitest?
