[horde] Browser.php non-object error

[JP Edwards]

Hi,

Horde Horde (horde) 3.3.10
Mail Mail (imp) H3 (4.3.9)

In var/log/apache2/error.log I've been getting errors to do with a "non-object" in /usr/share/psa-horde/lib/Horde/Browser.php'

A typical error line looks like:

[Tue Sep 18 07:23:55 2012] [error] [client nn.nnn.nnn.nnn] PHP Notice:  Trying to get property of non-object in /usr/share/psa-horde/lib/Horde/Browser.php on line 318, referer: http://webmail.mysite.co.uk/login.php

Same error also piling up for other lines in Browser.php e.g. 341 & 342, 754 & 756.

e.g.

line 318:  $this->_lowerAgent = String::lower($this->_agent);

line 341:line $agent = $this->_agent;
line 342: line $lowerAgent = $this->_lowerAgent;

line 754:  if (strpos($this->_lowerAgent, 'wind') !== false) {
            $this->_platform = 'win';
line 756:  } elseif (strpos($this->_lowerAgent, 'mac') !== false) {

Any ideas on how to fix this?

Thanks in advance for any suggestions.

Regards,

JP.
