Ubuntu 10.10, Midori 0.3.2 browser (same problem with Epiphany 2.30.2, Chrome 11.0.686.1 dev; haven't tried with Firefox as yet)

Proxychains-3.1 installed, working fine.

Here is the deal: when NOT proxychained, Midori or Epiphany can download and open a file (e.g. PDFs from a Google search) in Evince without problem.

But when proxychained, neither browser can open PDF files. The message is, "file xxx downloaded". Then it tries to open the file, an indication appears in the status bar, the turning wheel appears, and then nothing. Evince doesn't open. Whats going on here?

In both cases (with and without proxychains) files are downloaded to the /tmp folder. They have the same file permissions and ownership. Whats different when proxychained? Why can't the files be opened and why are there no error messages or notifications. Why the silent failure?

I don't want to use FF or Chrome. Chrome does not follow my GTK2 customizations and FF is just too resource heavy. Please help.
