Sorry to chime in on this a month and a half late. I'm just getting around to building digikam on OS X again. It appears that this addition to digikam is causing problems on OS X. Above, it is stated that this should on effect linux; however this appears to be triggering an old QT but in OS X. There is a bug report, which is 'fixed' with code that still appears to trigger there error
 
here's the old bug report -- supposed to have been fix in 4.7:    https://bugreports.qt.nokia.com//browse/QTBUG-2478
 
Now when i run digikam, i am seeing only thumbnails that are cached but can't access any pictures (i get an error, can't load file) in my albums and constantly getting the following error (reported in the above bug report):

  QKqueueFileSystemWatcherEngine::addPaths: open: Too many open files in system
  QFileSystemWatcher: failed to add paths: /Volumes/Home Directory/Pictures/Saved pictures/Pic0193.jpg
  QKqueueFileSystemWatcherEngine::addPaths: open: Too many open files in system
  QFileSystemWatcher: failed to add paths: /Volumes/Home Directory/Pictures/Saved pictures/Pic0194.jpg
  QKqueueFileSystemWatcherEngine::addPaths: open: Too many open files in system
  QFileSystemWatcher: failed to add paths: /Volumes/Home Directory/Pictures/Saved pictures/Pic0195.jpg
  QKqueueFileSystemWatcherEngine::addPaths: open: Too many open files in system
  QFileSystemWatcher: failed to add paths: /Volumes/Home Directory/Pictures/Saved pictures/Pic0200.jpg
  QKqueueFileSystemWatcherEngine::addPaths: open: Too many open files in system
  QFileSystemWatcher: failed to add paths: /Volumes/Home Directory/Pictures/Saved pictures/Pic0201.jpg

Is anyone else building digikam on OS X and seeing this error? Or is it just me?
