Sounds like the FileVault feature is causing some mayhem when enabled.

Panther FileVault data-loss misery
By Macworld staff

Mac OS X Panther-users have reported problems when enabling FileVault, a feature designed to protect user data, which seemingly doesn’t, in some cases.

Claims exist that FileVault has reset or destroyed data for Safari, Address Book, Mail, Keychain, and the Dock. Manifestations include Keychain being reset, but also ceasing to store user passwords any more; Mail messages and Safari bookmarks have also been lost.

OS instability can also result from the problem, with user posts on Apple’s support forums explaining that right now the only known fix is to format the drive and reinstall the OS.
