Most likely. The function you are referring to is a rather generic  
method though. It just encodes to JSON and obviously fails for because  
it gets some unexpected input.

You could either try to install xdebug  
(http://wiki.kolab.org/PHP_debugging) which should give you a more  
detailed stack trace of the warning. Or you try to add the following  
code in line 85 of /kolab/var/kolab/www/client/imp/lib/JSON.php:

if (!json_encode($var)) {
    Horde::logMessage(print_r($var, true), __FILE__, __LINE__, PEAR_LOG_ERR);
}

This would most likely output the problematic variable to the log.

Both types of output might help to identify where the problematic data  
comes from. I would assume you created some kind of encoding problem  
when copying data from the old to the new server.

Cheers,

Gunnar
