What is the significance of "czowOiIiOw=="

In my particular case, I'm getting this error after doing an ExpressionEngine update from 1.x to 2.x. There is a table that manages site preferences, and the data for each field is a serialized PHP array. After the update, any serialized array instead just says czowOiIiOw==. Googling this string brings up other non-ExpressionEngine-related site forums where end users are reporting seeing this string while being unable to login.

Does anyone have any idea what might be causing this, or have you seen anything like this before?
