[Koha] (no subject)

Hello Since I have done a bulkmarcimport searching isn't possible anymore. I allways get: Can't call method "as_usmarc" on an undefined value at /usr/share/koha/lib/C4/Search.pm line 2106. You can test it yourself on http://bibliothek.ksobwalden.ch Koha 3.0beta1 koha-opac-error_log tells me: http://bibliothek.ksobwalden.ch/cgi-bin/koha/opac-search.pl?q=werke koha@web-kso1:~$ What's wrong?
