I was able to recreate this using the steps provided on Ubuntu 15.04, however setting Chromium as my default browser in System Settings -> Defaults was insufficient. I had to launch chromium-browser, and then choose to set it as the default browser in its preferences. Also chromium-browser was closed when I clicked on the link in the synaptic. Is that also the case in your testing Christopher?
