I upgraded from 11.04 to 11.10 and Evolution refused to load after the upgrade. Luckily, I backed up Evolution data prior to upgrade.
Ubuntu 11.10 has changed the default email client from Evolution to Thunderbird. Please refer release notes for 11.10 - https://wiki.ubuntu.com/OneiricOcelot/ReleaseNotes
It would be advisable to warn all up-graders of Ubuntu 11.10 to backup their Evolution files prior to upgrade.
