I don't know much (being a bug triager, not an installer developper), but this looks suspicious. I will change the description of the bug, that sould attract developper eyes. Thanks a lot Ivà Burgos for helping us debug this piece of software. ** Summary changed: - Installer crashed on SAMSUNG SP1213C DVD reader + cramfs wrong magic on SAMSUNG SP1213C DVD reader -- cramfs wrong magic on SAMSUNG SP1213C DVD reader https://launchpad.net/bugs/67154 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
