Fixed, thanks.

trying to browse some SVN repositories with CHORA will only display 
the directories and no the folders.  I have tracked this down to the
lib/Horde/VC/svn.php file.

while trying to parse the svn change log for a file, there seems to be 
a slight error in the regular expression around line 730
  if (preg_match('/^r([0-9]*) \| ([^ ]*) \| (.*) \(.*\) \| ([0-9]*) 
lines?$/', $line, $matches)) {

If the author name contains a space this will not work.
changing the expressio to read:

  if (preg_match('/^r([0-9]*) \| (.*) \| (.*) \(.*\) \| ([0-9]*) 
lines?$/', $line, $matches))

will fix the problem.  (changed [^ ]* to .* )

This issue occurs if the repository does not have an Authors name (ie 
'no author') also.

Strange how this has gone so long unchecked..
