Lightroom 5.3 on Mavericks will not import from an SMB network share (OS bug in 10.9)

I have new Macbook running Mavericks and have just installed Lightroom 5.3 on it. I have also just moved my photos I have an SMB volume directly attached to my Asus router. This configuration is working fine for anything else I've attempted to do.

The problem I'm experiencing is in importing new pictures that I have added to the pictures directory on the SMB volume. Lightroom find the added files but can't generate previews and then when I hit the Import button, it comes back with an “Import Results” dialog claiming that all the new files “appear to be unsupported or damaged”. This is entirely false – the are normal jpeg files and Mac Finder and Preview have no problem opening the files. So this appears to be a bug in the Import function related to reading files on a SMB network share.

As a side note, when I first imported some new pictures in this configuration, I accidentally imported them to the Pictures folder on my Macbook. That worked fine. I then moved the folder containing the new pictures to the SMB volume from within Lightroom that that worked fine too. So the problem seems very specific to importing pictures that are already located on an SMB volume.

Hey, good news - I broadened my search a bit and and found the root cause and a workaround. See this page...

It turns out this is a well known problem with the SMB implementation in Mavericks. I modified my connection string to specify cifs instead of smb and my import is working fine now.
