[UPDATE: On Monday, Nov. 10, nearly a month later, Apple released Mac OS X 10.6.2, an extensive update that fixed the guest-account bug and more than three dozen other Snow Leopard problems. For a full list, see here.]

Call it fallout from the Sidekick fiasco.

Having watched Microsoft (MSFT) go through a weekend from hell for wiping out the personal data of thousands of T-Mobile (DT) customers, Apple (AAPL) finally acknowledged a data-swallowing bug that Snow Leopard users have been complaining about since September.

"We are aware of the issue, which occurs only in extremely rare cases, and we are working on a fix," an Apple spokesperson told CNET's Erica Ogg on Monday.

According to several hundred messages on Apple's discussion boards, the Snow Leopard problem is triggered when users log in and out of an old Leopard guest account and then try to log back in to their regular account. One victim described the effect as follows:

"Not only did Snow Leopard wipe out ALL of my documents, my email accounts, my address book, it broke the dynamic spell checker in yahoo messenger, caused random problems with Safari, InDesign, and others, caused lockups, spinning beach balls, loud fans… and it was just getting worse. I am restoring Leopard (sans snow) as I write this." (link)
