Thanks for pointing it out. I fixed the parser so that it understands
files with this, well, "interesting" document structure :) However, the
document in question seems to be problematic anyway -- Xpdf doesn't
display everything (OK, that might be because I'm missing some Asian fonts
here) and GhostScript even crashes completely :(
The patch will be included in the next upstream version, but if the
package maintainer is interested in fixing this with a new package
revision, there's also a patch against 0.10.2.
