Hi 

I have not used TeX-region for a while, but now there seems a bug.


With the setting

(setq TeX-output-dir  "build"
      TeX-region      "build/_region_")

There seems a bug, in TeX-region using the view command.

Steps to reproduce the error (see the attached file)

    1. Mark say the begin{frame} end{frame}

    2. Compile

    3. Run either C-c C-v or C-c C-r and chose view,

Then the viewer claims it cannot find the pdf file.

I bisected:

The first commit where the problem occurs is
c955473368fdffa7def3fbf03016fd0615a53528

While 

b650ab2847b1a775f36117f0d6077aecfff0419a

Is still ok,

Maybe I should have changed my setting?

Regards

Uwe
