Hi, it's caused by a virtual folder:
INBOX.IBX.Folder1 INBOX.Ordner.Folder1 INBOX.Ordner.Folder1.*OR (OR (OR HEADER FROM bar.com HEADER FROM bar.de) HEADER FROM foo.com) HEADER FROM barfoos.net NOT HEADER FROM root@ NOT HEADER FROM www-data@ SINCE 1-Jan-2010
When I delete the dovecot.index.search* files it works for a while but fails again.
