Bug#323963: advi: segfault or fatal error when scaling display

[marcus@better.se]

Package: advi
Version: 1.6.0-6
Severity: normal

When I launch 'advi' without arguments to display the help file
/usr/lib/advi/splash.dvi, the program crashes when I press '<' or '>'
to resize the text.

This happens nearly every time I press those keys, but it also worked
correctly once.

It seems that when I press '<' it terminates with this output:

  Fatal error when running: Xlib error: BadPixmap (invalid Pixmap parameter)

or sometimes segfaults with

  Warning: Graphics.Graphic_failure("Xlib error: BadPixmap (invalid Pixmap parameter)")
  Segmenteringsfel

However when I press '>', it terminates with a different message:

  Fatal error when running: Xlib error: BadDrawable (invalid Pixmap or Window parameter)
 
I tried this on two systems, both i386 running Debian testing with
some packages from unstable.
