PDF-file displayed incorrectly

I've filed this bug to Okular, but they redirected me here.

Someone sent me a scanned document which is displayed incorrectly in Okular. Namely, I see black bars above the text. Most other PDF viewers, such as xpdf, evince, inkscape, show this file correctly.

The "black bars" are apparently the OCRed characters, you can "select" them with the Okular Text selection tool.

Nevertheless, the rendering in Okular is (likely) wrong.
