#12610 closed defect (fixed)

Qt WARNING: libpng warning: iCCP: known incorrect sRGB profile

Reported by: Davidmh Owned by:
Component: other Version: VirtualBox 4.3.6
Keywords: libpng, warning, qt, srgb profile Cc:
Guest type: all Host type: Linux


When starting VirtualBox 4.3.6 on a Fedora 20, there are a lot of warnings complaining about invalid pngs like this:

Qt WARNING: libpng warning: iCCP: known incorrect sRGB profile

A list of the culprits can be generated with:

# find / -type f -name "*.png" 2>/dev/null | grep -i virtualbox | identify @- 1>/dev/null

On my box, there are 82.

This happens with the new, more strict, libpng 1.6.3, and the fix only requires recompile the corrupt pngs.

I have run convert {png} -strip {png} on all the files (sitting in /usr/share/icons/hicolor...) and now identify reports clean, but the warnings persist. I guess the profile has to be specified.

Same problem with SuSE 12.3. I also ran convert against all .png files that reported errors with identify, but VirtualBox still generates the libpng waning at startup. I recompiled the VirtualBox modules after repairing the .png files.

same problem here with 4.3.8, the fix should be quite easy, I report here a webpage as example to fix the images;

Can you post a build which solves this issue?

comment:5 by wonko1953, 9 years ago

See which contains a patch fixing this.

comment:6 by Frank Mehnert, 9 years ago

Resolution: fixed
Status: newclosed

Should be fixed since VBox 5.0.

comment:7 by VBoxGrl, 8 years ago

This is not fixed, I still see this problem with libpng-1.6.23 and Virtualbox 5.0.26
