Not entirely sure if this is related, but I had the exact problem described at http://bbs.archlinux.org/viewtopic.php?id=69035 and the solution there fixed it.
What happened there was that firefox was using EasyTag instead of konqueror/dolphin. Now, while this is slightly different, the fact is that firefox seems to be using /usr/share/applications/mimeinfo.cache for information about file associations, because when I removed EasyTag from there, Firefox started using Dolphin. Oddly, the next option (which I didn't delete) was Thunar, but this, apparently, was ignored. -- "Open containing folder" is only working if nautilus is present https://bugs.launchpad.net/bugs/133133 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
