Yes, that's correct. We use DBus to communicate between the main 
application and the rendering process. It seems to work, but I was not 
aware of these KIO slaves issues.

Using KDE Frameworks 5.29, currently with no install (everything inside a 
folder), and I can confirm that the KDE_FORK_SLAVES solution works.

However, now a new terminal window (cmd.exe) opens everytime kioslave is 
called. Any idea haw to prevent that behavior ?

Thanks a lot for taking the time to answer me, we are now very close to 
launch our Windows test version!

Best regards
