Different colors for pictures made from CMYK and RGB PDFs

We use ImageMagick as a command line tool to create thumbnails out of PDF files. This works great, but the result concerning the chromaticity is completely different when we use a RGB-PDF as the original file rather than a CMYK-PDF.
Which parameters can we set (and how) to get a consistent result?

Thanks, but unfortunately this didn't work.

What version of Ghostscript are you using? Perhaps an upgrade to the current version would help.
Perhaps converting from CMYK to sRGB via profiles might help.
