Now, exactly with the same source pdf file, but with a different parameter to imagemagick: convert -density 500 TUM_IAS_logo.pdf TUM_IAS_logo.png
(500 instead of 5000) everything works fine. All the above programs can open the file.
I still think this is a bug of imagemagick, because I assume no corrupted image file should make it to a SegFault. I guess the crash of nautilus, Unity, etc. are also because they use the same engine as eog to make the thumbnail.
