//#warning TODO Jörg, take a look at this
// JJ, 2012-09-07: We are now using the "...LastOpenedDatabase" keys for Aperture and iPhoto in com.apple.iApps.
//                 Let's see, whether the reported problem is reproducible with this implementation. We ar not using the corresponding
//                 "XMLDataFilePath" in Aperture or iPhoto preferences because at least in iPhoto preferences it currently
//                 points to a non-existing (!) file on my system. Not very trustworthy.

// This override of the same method in the superclass is just temporary, because Aperture 3.3 apparently doesn't
// reliably write its library paths to com.apple.iApps.plist anymore. However, this information can be found in
// com.apple.Aperture.plist, so we'll look in both places, combine the results (filtering out any duplicates) and
// proceed from there. 

// TODO: Jörg, please take a look at this and find a better workable solution for the future...
