Not sure why it happens only here, the construct Config.property=something is used frequently to modify the configuration. Edit - I guess it is because PixelOfflineCalibCondAlg not an instance of the configurable but the class definition on the removed line.
The second line with addFolderSplitOnline should be redundant.
