Thanks a lot Boud and Sven for the help and the how-to. Unfortunately, 
the patch return me :
> deevad at deevad ~/koffice/koffice-build/krita/plugins/paintops/libbrush 
> $ patch -p0 < ~/qtconcurrentmask.diff
> patching file kis_auto_brush.cpp
> Hunk #1 FAILED at 22.

But maybe this is too complicated for my user level to dive into , and I 
prefer here to follow the advice of Sven ;

I will not waste your time in asking you things about my patch/code/etc 
noob level skill ... :) Compiling and running will be my personal 
frontier; and keep feedback and test. I will not keep the bad usage to 
say my bug and complains in the mailing list or IRC too ; I will use the 
bugtracker tool.
