I am seing the exact same problem. On Kubuntu 11.10 both with usb- creator-gtk and usb-creator-kde.
The permissions of the file on NFS were 644 with me as the owner. Copying the file to the local harddrive fixed the issue immediately. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/567246 Title: usb-creator-gtk fails with opaque error when source .iso can't be read To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/567246/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
