RStudio preview 1.2.1086 on Windows 10, File Listing Error related to long pathnames

With the latest Rstudio Preview (1.2.1086) I'm getting an error when attempting to navigate to a folder. The dialog title is "File Listing Error" and the text reads
"Error navigating to <path>
The system cannot find the path sepcified

I suspected this may be a long pathname issue so I created a junction using mklink on my c:\ folder that links to a directory within the path, making the full pathname shorter using the link. Is this my goto workaround for pathlength issues. This allowed the path to load in RStudio.
