[horde] Call to undefined function: sethandlerobj()

[Hammad]

I upgraded php4, mysql on debian last night with lastest stable version of
horde, imp, turba ... etc.

php4: 4.3.10-16 from 4.3.10-15
php4-pear: 4.3.10-16  from 4.3.10-15
mysql: 4.3.24-10sarge from 4.3.24-10

I am now getting the following error everytime I goto horde main layout page and
'weather.com' and 'fortune' block doesn't show up. Everything was working fine
before the upgrade.

Fatal error: Call to undefined function: sethandlerobj() in
/usr/share/php/XML/Unserializer.php on line 852

    * IMAP Support: Yes
    * LDAP Support: No
    * Mbstring Support: Yes
    * Mcrypt Support: No

      The fileinfo PECL module or the mime_magic PHP extension (see below) will
most likely provide faster MIME Magic lookups than the built-in Horde PHP magic
code. See horde/docs/INSTALL for information on how to install PECL/PHP

Miscellaneous PHP Settings

    * magic_quotes_runtime disabled: Yes
    * memory_limit disabled: No
      If PHP's internal memory limit is turned on and if not set high enough
Horde will not be able to handle large data items (e.g. large mail attachments
in IMP). If possible, you should disable the PHP memory limit by recompiling
PHP without the "--enable-memory-limit" flag. If this is not possible, then you
should set the value of memory_limit in php.ini to a sufficiently high value
(Current value of memory_limit: 30M).
    * safe_mode disabled: Yes
    * session.use_trans_sid disabled: Yes
    * session.auto_start disabled: Yes
