Synchronized Browsing issue introduced in 4.2.5

WinSCP 4.2.5
Windows 7 (x64)
Connecting to WinSSHD 5.12 server

Since version 4.2.5, if I am locally and remotely at my windows home directory, synchronized browsing fails when trying to open any folder.
local: C:\Users\username
remote: / (which is mapped to the home directory on the server)

If I manually move into one of the remote folders, (and then correspondingly on the local folder), I can successfully use synchronized browsing.

Here are two screenshots:
