konsole settings and Terminus Bold font

After upgrading from Debian Stretch to Buster I had a problem, where konsole was re-setting its fonts preference.

The font I prefer is Terminus Bold, the bold part was going away though with each restart. It was odd and looked like a bug. I found this problem report:

It did not help though, so here is what worked in my case:

rm .config/session/konsole_*
