Macs don't have problems!!! <grin>

Or, maybe they do...

Quoting a Register article

***
The bug manifests itself as a request to regain lost disk space in the 
encrypted directory. If the user responds in the affirmative, 
FileVault's reclamation process damages the user's keychain data.

Apple last night said it was aware of the problem but was not 
recommending that users disable FileVault. Simply refusing to allow the 
software to reclaim lost disk space keeps the bug at bay.
