[ingo] No rules shown with sieve

[Hanns Mattes]

Hei,

after upgading, none of my rules are shown in ingo (well no rules at  
all are shown).

horde log says:

2013-06-05T16:04:27+02:00 WARN: HORDE [ingo] PHP ERROR: array_keys()  
expects parameter 1 to be array, string given [pid 7812 on line 116 of  
"/srv/www/htdocs/horde/ingo/lib/Factory/Script.php"]

Any Ideas?

Regards Hanns
