[opensuse-factory] imagemagick shows pngs with alpha channel

Hello, I create pngs with pyhton Pillow. Since a recent update imagemagick display shows my pngs transparently (black is transparent). However, it should know that the images have no alpha channel (identify is like display from imagemagick) identify cantilever_vts_80.png cantilever_vts_80.png PNG 719x719 719x719+0+0 8-bit sRGB 27241B 0.000u 0:00.000 The image is properly displayed with gimp and gwenview. Shall I rise a bug? Thanks, Fabian
