Hi!

When I try to typeset an XSL-FO-file with XEP client 3.42 with the ant 
task, the program dies with the following stacktrace:

If I call XEP directly, the message is:

[...]
[page-number 64]
{!list is not a pair}

This looks to me like a bug. Even if not, the error message is hardly 
helpful.

Best regards,

Marc
