Comment 12 for bug 776393

Had this problem with latest Natty as of 24 May. Chromium was unable to set itself as the preferred browser. Using Preferred Applications did not seem to work initially, I suspect this is because Chromium was open at the time. At some point I closed Chromium, set the option in Preferred Applications, opened Chromium again and noted it was now correctly the default browser.

What was interesting was that once I had successfully got Chromium set as the default browser, Chromium can now set itself as the default browser henceforth - ie. this problem can perhaps only be seen on a freshly installed system.
