svn 1.7 client issues error on update of single file externals

Using subversion 1.7(.5), updating a working copy that has single file svn:externals results in an error, even if the update does indeed work.
Bug, or am I doing something wrong?

Details posted on stackoverflow.com (before I was aware of this mailing list):

And the content of the above url:
I have come across an error using svn update on a working copy folder with single file svn:externals. I wonder if there is a work-around for this, if I am doing something wrong, or if this is a bug in the client 1.7.x of subversion.

The error occurs when calling svn update using subversion 1.7.5 (tried TortoiseSvn 1.7.7 and slikSvn 1.7.5) on a folder that has single file svn:externals. I'm tempted to say it's a bug in the subversion client, because the update does indeed occur, but it says it fails.

For reference, the server side uses a very old version (1.1.4 [r13838]), but from what I know externals is a client "feature" so an old server should not be a problem. Besides, this workes well using subversion 1.6.x (client).

This is the scenario I observe:

1. Checkout a project (that has single file svn:externals)
   svn checkout http://my/repo/projects/proj1 proj1

2. Browsing to the folder in my working copy with single file svn:externals.
   E.g.
   myFile.txt http://my/repo/components/comp1/myFile.txt

3. Executing svn update and I get the following output:
   Fetching external item into 'trunk\proj1\source\myFile.txt':
   : warning: W160016: Failure opening
   '/components/comp1/myFile.txt/myFile.txt'

If change the svn:externals so that the local file has a different name, like below:
   my_file.txt http://my/repo/components/comp1/myFile.txt

Then the error message in 3. becomes as below, so the the file after the last
forward slash ('/') is the local version of the file.

   Fetching external item into 'trunk\proj1\source\myFile.txt':
   : warning: W160016: Failure opening
   '/components/comp1/myFile.txt/my_file.txt'
