    Revert "Use plain gdk_pixbuf_loader_new(), not new_with_mime_type()"
    
    This reverts commit 31d5eded183dd33bec9ac52c47a6f4a97c4eea33.
    
    Turns out that MIME detection based on file data only works for types
    that have magic bytes defined in the MIME database. Checking the MIME
    type in eog has the advantage that the filename is available as fallback.
    
    Fixes #124.
