Chromium can't be set as default browser

[Nicholas Krause]

I've tried setting chromium-browser to be the default browser by either xtools,lxde tools or just uninstalling firefox. Nothing seems to make it stop warning me about being a non default browser.

Have you tried using chromium's built-in setting to set itself as the default browser?
Just browse to chrome://settings/defaultBrowser and click the button (under the covers this calls `xdg-settings set default-web-browser`).
