[horde] /usr/share/horde3/lib/Horde/Prefs/UI.php error

[Jacques Leyrat]

Hello,
After an upgrade from horde 3.0.4-4 to horde 3.1.3 and imp 4.0.2-2 to 
4.1.3-4 (Debian Sarge to Etch upgrade), I have the following problem:

Using the "Deleting and Moving Messages Option" generates the following 
errors:

*Warning*: generateui(/usr/share/horde3/lib/../templates/prefs/.inc) 
[function.generateui 
<http://testimap.unicaen.fr/horde3/services/function.generateui>]: 
failed to open stream: No such file or directory in 
*/usr/share/horde3/lib/Horde/Prefs/UI.php* on line *209*

*Fatal error*: generateui() [function.require 
<http://testimap.unicaen.fr/horde3/services/function.require>]: Failed

(include_path='/usr/share/horde3/lib:.:/usr/share/php:/usr/share/pear') 
in */usr/share/horde3/lib/Horde/Prefs/UI.php* on line *209*

As it seems to be related with Horde prefs, I tried with the 
distribution prefs.php, which gives the same error.

Can anyone help with ideas to solve this problem ?
Thanks
