Indeed, as without a config directory we can't map something like "Ubuntu 15.04" to "wily", which we need to download the matching Contents.gz.

I turned the warning into a fatal, which should already help: http://bazaar.launchpad.net/~apport-hackers/apport/trunk/revision/2997 . This should be okay, as realistically the first apport.packaging.install_packages() call does not really do anything (unless you specified extra_packages), as we usually have ProcMaps available in reports and thus use the needed_runtime_packages() pass to install only the packages we need instead of all Packages: plus Dependencies:. So I think any additional potential speedup by reordering things should be miniscule, especially since (hopefully) an unknown ExecutablePath isn't the common case?
