            Bug ID: 189230
           Summary: Shipped PNGs include bad profiles: iCCP: known
                    incorrect sRGB profile
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

There is bad metadata embedded in some of the PNG icons shipped with WebKit.

These lead to warnings being printed to the terminal as libpng complains about them: "iCCP: known incorrect sRGB profile"

This affects software using WebKit as library as well.

https://stackoverflow.com/questions/22745076/libpng-warning-iccp-known-incorrect-srgb-profile has a nice overview and proposed fixes for removing this bad metadata.

This is a list of the affected files:

Please remove the buggy profiles so that unnecessary warnings are not printed to users and developers.
