[Zope] wrong content-type from Z Search Interface

Hi, I'm having some strange problems with a Z Search Interface. With some queries it returns wrong content-type (octect-stream instead of text/html). How can I fix this? Where is the problem: dtml-code sligth modified by me (most aestetical changes) or sql data returned by MySQL? The problem is reproductible: whenever I try some keywords, I get a download prompt instead a html rendered page.
