Not a bug in ccleaner. Chrome and Firefox store their cookies in a database file. When they are running that file is locked from access by other software (ccleaner for example). The following are the most common reasons for chrome not exiting: Chrome Sync, Cloud Print, other Background services, chrome Apps, malformed Plugin.
