Can't go from package version number to info about that version

[Matthew Paul Thomas]

1. On <https://errors.ubuntu.com/>, click on any of the package version numbers.

What happens: Nothing.

What should happen: You see more information about that version -- who uploaded it, and what the changelog was -- that will help you in discovering how the bug was introduced.

I suggest going to the Launchpad page for that package version. E.g. clicking the "0.126" in the row for an update-notifier error would go to <https://launchpad.net/ubuntu/+source/update-notifier/0.126>.

I'm unhelpfully glossing over the distinction between source and binary packages. Launchpad doesn't seem to have architecture-independent pages for binary package releases, perhaps because a single source package may produce different binaries for different architectures.

Yeah, the lack of a mapping from binary packages back to source packages in the Launchpad API is a source of constant frustration. However, we've already dealt with this so that we can file bugs against the correct source packages from that table. There's a SourcePackage column that we can get, given the crash signature.

Of course it's potentially slow as it hits the OOPS column family for every signature it has to process, rather than relying on this data being duplicated into the BucketMetadata column family. We may want to optimise this by doing the latter in the future.
