Comment 4 for bug 88229

Thanks for taking the time to report this bug and helping to make Ubuntu better. However, this bug is a duplicate of bug 87627 and is being marked as such. That bug deals with USB devices being mounted noexec (with no execute permissions) as opposed to exec which is the way they used to be. An update to gnome-mount has been released and that should resolve your issue. Feel free to submit any future bugs you may find.
