Save as PDF+LaTeX doesn't respect export region for text export

Inkscape 0.48.5 r10040

Open attached "inside_outside.svg" with Inkscape. You see one box containing the text inside, and one box containing the text outside. The box inside is located inside the document page, the other one is located outside.

Now save this file as pdf. In the pdf settings dialogue make following preferences:
Restrict to PDF version [PDF 1.5] (but I think this doesn't matter)
Convert texts to paths [ ]
PDF+LaTeX: Omit text in PDF, and create LaTeX file [X]
Export area is drawing [ ]
Export area is page [X] <-- this one is relevant

Click okay.

So you get two files:
* inside_outside.pdf
It's all okay here, the file contains of one box as it should

* inside_outside.pdf_tex
next to some comments and necessary LaTeX stuff, this file contains two lines (line 53 and 54 for me) including our text:
    \put(0.50846671,0.70846671){\color[rgb]{0,0,0}\makebox(0,0)[b]{\smash{inside}}}%
    \put(1.50846667,0.70846671){\color[rgb]{0,0,0}\makebox(0,0)[b]{\smash{outside}}}%

The first line is perfectly okay, it should be there becaus its the "inside" text for our first box.
The second line shouldn't be there (this is the bug!) because it's the text for the "outside" box, that we didn't want to export.
