Does the dpi of the display that X reports differ between the machines? The 
last time I have seen strange font sizes it was because the reported dpi of 
the display differed from the default 96x96. You can check with
xdpyinfo | grep -B1 dot

That would not explain why it differs between restarts of Konsole, but is the 
first thing you should check.
