Chrome constantly makes itself the default browser: overrides default mime settings

[arky]

Chromium adds these MIME entries that over the default browser (firefox nightly) settings on my computer. This quite annoying because I have set Chromium not add itself as default browser nor check for it.

Even after I delete the entries, Chromium adds them on next reboot. This *really* bad !

Where have you installed chromium from? It doesn't look like from an ubuntu package.
