Bug#292616: kdvi fails to display some characters of virtual fonts properly



Subject: kdvi: fails to display some characters of virtual fonts properly
Package: kdvi
Version: 4:3.3.2-1
Severity: normal


KDVI does not display virtual fonts properly. As it seems KDVI sometimes 
fails to switch to the appropriate base fonts.

Here is an example tex file with two short formulas:

\documentclass{article}
\usepackage{mathptm}
\begin{document}
$  f(x,z)=xy$

$ f\leftharpoonup x,z \leftharpoondown / xy $
\end{document}

(Resulting dvi file attached)

The two formulas look different when viewed with xdvi, which is
the result I expected. But viewed on kdvi both formulas look the same
except for spaces. Setting kdvi to use type 1 fonts with/without
font hinting does not matter, whereas canonicalising the dvi file with
dvicopy before running kdvi results in a correct display.
