Web Inspector provides server-side compression advice to files that do not originate from a server. (For example, inspecting Web Inspector determines that its own code could be sped up using zlib?) I've included my fix, a patch to inspector/Resource.js to add one extra check (to verify non-local origin) before marking a resource with this tip.
