[Bug 36817] won't open pdf's

Affects: nautilus (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I can't open pdf's from nautilus anymore.  It complains that "The
filename "letter.pdf" indicates that this file is of type "PDF
document". The contents of the file indicate that the file is of type
"plain text document". If you open this file, the file might present a
security risk to your system."

Well DUH
OF COURSE pdf files look like text files.

This problem seems to happen for all pdf files that are generated by
dvipdfm, even though all those documents are correctly identified by
file as pdfs, and evince, xpdf, acroread and gv can display them
correctly.

PDF's generated directly by pdflatex or by ps2pdf work fine.

This is on dapper with nautilus 2.14.0-0ubuntu3 and tetex-base
3.0-15build1.
