Right; PEAR_Error is kind of like exceptions for PHP 4 (which didn't  
have exceptions). It's not a problem with the PEAR install, it's an  
error being returned from the VC functions - in this case browseDir,  
which is trying to list the files in the top level of the repository.

Look in your Horde framework dir - framework/VC/VC.php, or  
framework/VC/VC/svn.php (or libs/VC/svn.php depending on what  
framework setup you have).

http://php.net/var-dump is a good starting point. If you want to  
create the Horde error box with a debug message, you could do  
something like:

$GLOBALS['notification']->push(var_export($variable, true), 'horde.error');
