Weird message on Mac OS High Sierra (file choosing)

Hi, today I have upgraded my mac OS to High Sierra. Upon file choosing (FileChooser) I got the following message:
objc[3613]: Class FIFinderSyncExtensionHost is implemented in both /System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit (0x7fff925f0c90) and /System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride (0x10b755cd8). One of the two will be used. Which one is undefined.

File chooser works ok, however.
Has anybody experienced the same?
What’s the remedy?

I’m getting this as well. I haven’t noticed any problems occurring due to it though (like the month 13 out of bounds bug).
