Public bug reported:
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?

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