svn export URL of a file with svn:special fails on Microsoft Windows

[This is intended as a bug report...]

In my repository, I have one file which is a symbolic link used only in
builds for other machines. It is, of course, checked out with the rest
when I use svn commands on Microsoft Windows, but appears as a normal
file.

The svn export command fails when it gets to this file, with message
"E720032: Can't remove file 'svn-<RANDOM>': The process cannot access
the file because it is being used by another process." If I use "svn
export PATH1 PATH2" to do the export from a working copy, the file is
copied without any error message.

I expect svn export to work (and produce a small plain file on Windows)
for files with the svn:special property.

Here's what my file looks like.

  svn cat svn://localhost/repos/trunk/Current
  link A
  svn proplist svn://localhost/repos/trunk/Current
  Properties on 'svn://localhost/repos/trunk/Current':
    svn:special

Here is what happens when any "svn export URL PATH" command reaches it.
There is a pause of a few seconds, then the message.

  svn export svn://localhost/repos/trunk/Current Current
  svn: E720032: Can't remove file 'svn-DBFBE990': The process cannot
access the file because it is being used by another process.

Possible workrounds for this bug: (a) use svn checkout, or (b) use svn
export from a working copy.

  svn --version
  svn, version 1.7.9-SlikSvn-1.7.9-X64 (SlikSvn/1.7.9) X64
