Comment 3 for bug 972279

after tweaking around in the graphical profile configuration dialogues without much success i found the autogenerated .colorscheme file for my current profile in .kde/share/apps/konsole, in my case 'WhiteOnBlack.colorscheme'
after setting the 'Bold' parameters of the 'Intense' color entries there to 'true' and restarting konsole it works as expected at least for my font/size for now. couldn't get it to work with Monospace either.

.kde/share/apps/konsole/Shell.profile:
[Appearance]
AntiAliasFonts=true
BoldIntense=true
ColorScheme=WhiteOnBlack
Font=DejaVu Sans Mono,9,-1,5,50,0,0,0,0,0
