I found the same problem. On windows I fixed it with installing Inkscape
version 0.48 but I cannot do this under ubuntu 16.04. Therefore I wrote
a script in python. There is my simple script for converting .svg images
to .pdf_tex format:


'''
Inkscape 0.92 have a bug while exporting svg image to pdf_tex.
The pdf_tex my be quite usefull while writting manuscripts in Latex:
https://waterprogramming.wordpress.com/2015/07/28/embedding-figure-text-into-a-latex-document/

The problems is because number of pages in pdf and pdf_tex and exported 
files usually differs (bug). Both options are possible: number of pages 
in pdf can be higher or lower to the number of pages, specified in pdf_tex 
file.

Presented solution is tested on Ubuntu 16.04 and is written in python 2.7 
(pypdf is only available for python 2).

Run this script: put svg figure name as argument:
python pdf_correct.py figure.svg

Title:
  PDF+Latex export creates multipage pdf, pages missing

Status in Inkscape:
  Confirmed
Status in inkscape package in Ubuntu:
  Confirmed
Status in inkscape package in Debian:
  Confirmed

Bug description:
  In 0.91 the z-order information in svg is used to create multipage
  PDF+LaTeX documents as per bug 771957. However, for the SVGs I have
  been converting to PDF+LaTeX in this way, the TeX-file instructs to
  load more pages than the PDF has, for example the PDF has only three
  pages and the TeX file also includes page=4. This basically breaks the
  PDF+LaTeX export for me and I have to use EPS+LaTeX + epstopdf
  package.

  The bug occurs on OpenSuse 13.1 and Windows 8.1.

  Attached a zip file with two svg files and their broken PDF+LaTeX
  counterparts.
