[horde] [Horde 4.0-git] Blank page after having configured imp

[Gerard Breiner]

Hello,

Working Environment :

Horde 4.0-git on a Debian Lenny
The repository path is : /www/horde-git
The horde path symlinks is : /www/horde4  and I created a link 
/www/horde ---> /www/horde4

The problem

Just after having configured imp by using the horde interface it  takes 
a long time and eventually display a blank page.
The horde.log tell me that the connection has been successfull and no more.
In order to confirm that this problem is caused by a bad configuration 
of imp (I supposed in registry.php ?) I set it up as "inactive" in 
/horde/config/registry.php  and delete cookies afterward I can again to 
have access at the horde interface.

Thanks in advance for any help

Best regards
