[imp] fatal error editing imp prefs after 5.2.7 upgrade... again

[cdj at deskservice.com]

Hello, i've just read from archive :
http://lists.horde.org/archives/horde/Week-of-Mon-20140901/052537.html
but it's not my case.

I've NO prefs.local.php.

But the error is the same, when i try to edit prefs from imp : 

  è AVVENUTO UN ERRORE FATALE
