2.2.4 build issue

[Bertalan Fodor]

When compiling lily-753313481.ly

\paper {
   linewidth = 160 \mm
  
   indent = 0.0\mm
   raggedright = ##t
}
\score{
   \notes\relative c''{
       c-2
\stemUp
f
   }
}

lilypond 2.2.4 generates a bad tex file: it has the line:
\lyitem{-07.0000}{000.8500}{\magfontKs{000.0650 000.0650 -02.1878 
004.5000 000.0700 draw_round_box}}%
instead of

But magfontKs doesn't exist. Lilypond 2.2.2 generates the following from 
the same input:

\lyitem{-06.0000}{008.8150}{\embeddedps{000.0650 000.0650 003.0000 
000.3122 000.0700 draw_round_box}}%

Thanks,

Bert
