utf-8 decomposed characters in path to the working copy prevents tree view from working

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Check out a working copy into a path with UTF-8 NFD character.
2. Open the WC with tree mode.

What is the expected output? What do you see instead?
The folders and files are expected to be shown.
Instead, svnX seems to be looking for something forever and the content will 
not be shown.
If the number of NFD character changes, the result also varies. Sometimes, the 
folders are partially shown.
Doesn't seem to affect the flat view mode.

What version of the product are you using? On what operating system?
SvnX 1.3.4
MacPorts subversion @1.8.8_0+unicode_path
Tried on two Macs; one running Mavericks, the other Lion.

Please provide any additional information below.
Thank you for the patch you provided to subversion, and eventually to MacPorts, 
for svn 1.7.

MacPorts got a contribution to make the patch work on 1.8, but seems to need 
more fix to be used with svnX.
