Try mounting an smb share with gnome vfs, aand double clicking an html file in
there. It won't open.

Somebody got the wrong bug

[Kent Lion (kent-lion)]

I don't know how to get this to the right people, but I found this "bug" and the one it's supposedly a duplicate of via the Google search:
ubuntu error "Cannot change to folder because it is not local"
...and I believe it is not a Mozilla Firefox bug, but an OS bug. I'm very new to Linux (XUbuntu), and don't know enough about it to know what the problem might be, but here's my story. The first time I had contact with XUbuntu was on an old 500 MHz machine in Germany. XUbuntu was installed for me and I was on my own. With some playing around, I eventually managed to get Listen Media Player to play streams of my PBS radio station in Hampton Roads. When I got home, I installed XUbuntu on an old machine, and was never able to get it to play radio streams. Eventually, in my attempts to get Listen Media Player to work, I tried "upgrading" it with info from the developers' web site, and that was the end of a functioning Listen Media Player. Even completely uninstalling and reinstalling it doesn't work. I never did try playing a CD with Listen Media Player.

Next I tried other media players, and was eventually able to get Rhythmbox to do the job, but it wouldn't play CDs. Then I installed Audacious. I never did find informationon Listen Media Player, but Audacious wasn't any better in that regard; so I have no idea how to even try to get Audacious to play a radio stream. However, when I click the play button, a selection dialog opens inviting me to select a CD track to play. The DVD or CD drive with an Audio CD in it shows up, but when I select that drive, I get the error message:

The folder contents could not be displayed
Cannot change to folder because it is not local

Note that in this case, the CD was in cdrom0, the DVD drive. After that, when I press the play button, neither the DVD nor the CD drive are visible, and the remote file system app (Gigolo) shows cdrom0 as unmounted, Audio Disk as mounted and no cdrom1. If I then click on the Audio Disk in Gigolo, it disappears. If I physically eject the DVD drive with the Audio Disk in it, it and the other drive shown as mounted disappear. It's as if the 2 CD drives are being confused. If I then try to remount cdrom0, I get the following error message:

Connecting to "cdrom0" failed.
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

So I tried: dmesg | tail
