I am using calibre 0.9.6. The --no-default-epub-cover option seems to work only for EPUB-Output, but not for MOBI.

This wouldn't be a big problem, but the viewer stretches the image, destroying its aspect ratio. Another strange thing is that it selects a tiny .png-file, which comes after a .jpg-file in the document. The .png-file is actually the last image in the document.

There is no option to prevent this (--preserve-cover-aspect-ratio works only for PDF). There's also no option to disable the automatic cover image at all, when converting EPUB to MOBI.

How can the stretching of the cover image be prevented? All other images are not stretched.

I tried a white pixel (1x1.gif) as first image... but ebook-convert still picks the .png-file at the end of the document.
