Comment 3 for bug 442810

Indeed, that was at least part of the problem. The output was:
/usr/local/firefox-3.5/firefox "%s"
So I ran: gconftool --unset /desktop/gnome/url-handlers/http/command
and now it's a more reasonable firefox %s.

But now, if I run ubuntu-bug, after it collects the information it says, on stdout,

Error showing url: Failed to execute child process "/usr/local/firefox-3.5/firefox" (No such file or directory)

yet it actually runs the installed firefox and loads a launchpad page. Restarting apport with "service apport restart" didn't help. I'm not sure where it's still getting the old string (I haven't tried rebooting).
