I found the problem. MediaWiki more or less constantly provide Thumb.php with a width that is 1 pixel too large, which makes Thumb.php generate an error. This applies for images that are smaller than the standard size for thumbnails and the image previews at the image articles.
A bug in MediaWiki? Or something wrong with my configuration?
Example: I have an image that I try to view with [[Image:MyImage.jpg|thumb]], which creates a thumbnail with URL http://my-server-url/w/thumb.php?f=MyImage&width=170, which says " Image was not scaled, is the requested width bigger than the source?" Manually changing the url to http://server.com/w/thumb.php?f=MyImage&width=169 makes the image show up..
The same for an image that does not show up on the image article. The preview image has URL http://my-server-url/w/thumb.php?f=MyOtherImage&width=369, which says: " Image was not scaled, is the requested width bigger than the source?" Manually changing the url to http://server.com/w/thumb.php?f=MyOtherImage&width=368 again makes the image show up..

Edit: It seems like thumbnails have been shown via thumb.php before also, but still some thumbs are not showing up, even though the image files are there, and the images are not displayed at the image articles. // Samuel

and if they are shown they are shown via the thumb.php file only, even though the thumbnail is created in the thumb directory (a new one is created if I delete it and refresh the article).
