DistributionSourcePackage:+index incorrectly links versions with epochs

[Alberto Salvia Novella]

HOW TO REPRODUCE:
1. Go to (https://launchpad.net/ubuntu/+source/unrar-nonfree).
2. Click on a package.

RESULT:
Instead of showing the information from that package, Launchpad redirects to a blank page.

This all works for me. Which link in particular did you click on? Were you logged in at the time, or not?

[Alberto Salvia Novella (es20490446e)]

Only happens in Chromium and Chrome, but not in Firefox. Not matter if you are logged in or not, if all the extensions are disabled, or even if you run it from the Ubuntu guess session.

The link could be any package under the Ubuntu releases names. Moreover right clicking on those does not show the "open link in new tab" or "open link in new window" options in the drop menu. On the other hand clicking on the names themselves works.

Here's a recording of the problem:

I see - thanks for the detailed explanation. I believe that this is because the colon in the package's version isn't being URL-encoded in that link, so Chrome/Chromium takes a strict interpretation of it as an unknown scheme or similar while Firefox tolerates it. RFC 1738 is clear that we should be URL-encoding the colon.

Fixed in stable r18206 <http://bazaar.launchpad.net/~launchpad-pqm/launchpad/stable/revision/18206>.

Yeah!
