    Description

      Hi,

      QtSDK installed (4.7.4) and recompile an application (that works perfectly) that reads images .png,
      and it crashes when trying to read any file .png.

      libpng warning: Interlace handling should be turned on when using png_read_image

      Up to version 4.7.3 it didn't happen.

      This problem was also reported in QtCentre
