QtQr can not decode a QR code in PNG format

Hello Rául,

Thank you for your report. Could please tell us what operating system are you using and QtQR version please?

Please test using the daily PPA version and check if the problem persist.

Thanks in advance.

Best regards.

I am using Kubuntu 17.04.
QtQR version available in 17.04 repositories is 1.4.0~21.

The latest version available in the daily PPA can decode the PNG file. Still, it shows this warning:
/usr/lib/python2.7/dist-packages/PIL/Image.py:872: UserWarning: Palette images with Transparency expressed in bytes should be converted to RGBA images
  'to RGBA images')

Will this new version be available in (K)Ubuntu 17.10? Currently the PPA only has builds up to Ubuntu 16.10 (I installed the package from the repository of that release).

Thanks.

Thanks for all the debugging! Yes it will be available in the PPA, and
hopefully the repo version too.
