How to hide SVG warnings in console?

[RazrFalcon]

My program loads many SVG files and I get a lot of warnings in console:
@Could not resolve property : linearGradient4636
Could not resolve property : linearGradient4592
Could not resolve property : linearGradient4247
link XMLID_10_ hasn't been detected!
link g4868 hasn't been detected!
Could not resolve property : linearGradient4112
Could not resolve property : XMLID_29_
link XMLID_36_ hasn't been detected!
// and much more
@
How can I disable it?

Probably by fixing your SVG files? :)

Seriously -- reading the Qt source doesn't give any valuable information about suppressing them?
