I can reproduce the bug, in effect, the PDF output is
blank... If I get your fit_dec0.985_0_6.pdf file, then
I translate it to JPEG, then I link the obtained JPG
file from inside another TeXmacs document, then the
TeXmacs PDF output works for this very document.

And then, if I translate this JPEG file to PDF again, I
obtain a PDF file that perfectly works when it is linked
from inside a TeXmacs document (namely : such a TeXmacs
document can be exported correctly either to PS or to PDF).

Conclusion : the problem clearly stems from the
particular PDF dialect that is used in your PDF
images.

More precisely, I just checked, the PDF version
number in your original PDF file is :
[[
  %PDF-1.4
]]

On the other hand, the PDF version number in
the correctly linkeable PDF (and the one in
any TeXmacs's PDF output is) :
[[
  %PDF-1.2
]]

So the problem is not solved :-(, and the
question open to us becomes : why does TeXmacs
understands PDF 1.4 only for viewing and not
for printing ?
