I have finally been able to reproduce the blank page error consistently.

I recently received one email with a 8+MB attachment.
Every time I try to open this email in horde, I get a blank page.

Looking at the logs, there is nothing in either
/var/log/apache2/error.log
or in
/tmp/horde.log

/tmp/horde.log contains only login success and logout lines.
This is totally useless!

 From this behavior it is clear that there is a memory limit that  
stops the execution to a
blank page.
Shouldn't the error be catched and an error message returned to the  
user instead of a blank page?

In my conf.php file, I have:
$conf['debug_level'] = E_ALL;
$conf['log']['name'] = '/tmp/horde.log';
$conf['log']['type'] = 'file';
$conf['log']['enabled'] = true;

$conf['fetchmail']['size_limit'] = '10000000';
$conf['compose']['attach_size_limit'] = '0';

So my questions are:
1) How can I disable the NO error_reporting() in horde?
  Where is the switch that would put back horde in testing mode?
2) Why the error(s) is(are) not reported in the logs (horde or apache)!
