Program Error steamwebhelper.exe when starting winesteam

I have been consistently getting this error and have no idea if it’s fatal or ignorable but either way; how does one fix / or get rid of it?

It looks like this bug:
And it looks like you can get rid of it by choosing WinXP as the emulation mode instead of Win7

This can be safely ignored, hopefully this will be fixed in future versions of wine. I added the --no-cef-sandbox option to workaround this bug but as Xodetaetl said, it will only work in WinXP mode.
