If we don't have xdg-open, try - * the appropriate launcher for the environment, but ignore - * the return code from kfmclient, as it might be bogus (that's - * the bug xdg-open works around). - * - * Otherwise, try the "broken/unpredictable browser launchers", - * but run them in the background and leave them running, and - * ignore the exit code, and then try x-www-browser, and then - * try directly launching a user-specified browser.
