This is not a bug. You have to escape the '[' character with a backslash, otherwise it's detected as the start of a control tag. If you're using the v0-7 branch, and do not need the text parsing facilities you can disable parsing on a per window basis, or set a system wide string parser (such as a CEGUI::DefaultRenderedStringParser instance) to disable it completely.
