The file I've attached may be malformed in some way but this still shouldn't cause a crash like this.

Here's a shorter test file that crashes immediately.

I can view a pdf file created from the same input with no problem.

And here's minimal TeX source to produce this error:

\font\secsl=cmbxsl10

{\secsl keyboard-characters}

\bye

I was unable to reproduce the bug with the current version of xdvik. The bug report refers to version 22.84.9, which dates back to 2004 or early 2005. The handling of Type 1 fonts has been rewritten since then, so I doubt very much that the bug still remains (in any form).

[Gavin Smith]

Okay, thanks for investigating.
