[wxMac] Random successes open files via wxFile

Hi,

I'm experiencing an odd problem when opening files with wxFile. Probably 
about 60% of the time it
fails with error 2 (no such file or directory). All the files I am testing 
with are in the same folder,
all are owned by my user and all have the same permissions. To confuse the 
process further, I duplicated
(in Finder) one of the files that couldn't be read and the duplicate could 
be read but the original still fails.
If I run the program again, I get exactly the same results. i.e. the same 
files succeed and fail.
The files are a mixture of sizes and types.

If I roll my wx library back to 10 Aug 2007 then this all works fine.

Below is a testing method

  wxString aDir = ::wxDirSelector(_T("Select the source directory."));
  if(!aDir.empty())
  {
      wxPuts(_("Dir selected.")+aDir);
      wxDir dir(aDir);
            if ( !dir.IsOpened() )
      {
          wxPuts("Error opening directory.");
          return;
      }
      wxPuts("Enumerating object files in current directory:");
      wxString filename;
      bool cont = dir.GetFirst(&filename, _(""), wxDIR_FILES);
      while ( cont )
      {
          wxString file = aDir + _("/") + filename;
          wxPuts(file);
          wxFile fsIn(file);
          if ( !fsIn.IsOpened() )
              wxPuts(_("ERROR: couldn't open file."));
          else
          {
              wxPuts(_("File opened."));
              fsIn.Close();
          }
          cont = dir.GetNext(&filename);
      }
  }
  else
      wxPuts(_("No dir selected."));

Using wxSVN head - debug/unicode, Intel Mac with 10.4.10, gcc 4

Cheers
Dave
