I experienced the same issue, after a fresh reinstall of Jaunty yesterday. I also had my encrypted lvm partition created by an earlier ubuntu release and it was named sda5_crypt. The script which is responsible for parsing crypttab seems to be in /usr/share/initramfs- tools/hooks/cryptsetup . Bug 332950 finally helped me out, I replaced the mentioned script with a patched version, which at least gave a more descriptive error message.
