See the page that you linked to, under the text "no decode delegate for this image format". The problem is either that you haven't installed delegates, or that ./configure can't find them.
I found a solution.
After the delegate has worked, I found the error. The error was due to text files created in Windows. I copied the text and wrote it into new files in Lubuntu. So it worked. What should be broken on the text files, I do not know. Maybe it's a bug in ImageMagick.
Strange is that there was the problem with very few text files. For many, there were no problems even in older versions of Imagemagick.
