unable to decode qr code from image file

[Muelli]

zbarimg --verbose=7 /tmp/qr.png
scanned 0 barcode symbols from 1 images in 0.1 seconds

WARNING: barcode data was not detected in some image(s)
  things to check:
    - is the barcode type supported? currently supported symbologies are:
      EAN/UPC (EAN-13, EAN-8, UPC-A, UPC-E, ISBN-10, ISBN-13),
      Code 128, Code 39 and Interleaved 2 of 5
    - is the barcode large enough in the image?
    - is the barcode mostly in focus?
    - is there sufficient contrast/illumination?

dump_stats: symbol sets allocated = 1
dump_stats: scanner syms in use = 0 recycled = 0
dump_stats: image syms in use = 0 recycled = 0
dump_stats: symbols allocated = 0
dump_stats: recycled[0] = 0
dump_stats: recycled[1] = 0
dump_stats: recycled[2] = 0
dump_stats: recycled[3] = 0
dump_stats: recycled[4] = 0
_zbar_qr_destroy: max finder lines = 511x511

I expected zbarimg to decode the image, because when using zbarimg on OpenSuSE it correctly decodes.
