Note: this SVG file also exhibits the following export error:

https://bugs.launchpad.net/ubuntu/+source/inkscape/+bug/1417470

I fixed it by using the following definition of \includesvg, inspired by
one comment in the above bug:

\newcommand{\includesvg}[2][]{%
\executeiffilenewer{images/#2.svg}{images/#2.pdf}%
{\unexpanded{PDF_FILE="./images/#2.pdf"; inkscape -z --file=./images/#2.svg --export-pdf=$PDF_FILE --export-latex; sed -i 's/\\\\/\n/g' ${PDF_FILE}_tex; MAXPAGE=$(pdfinfo $PDF_FILE | grep -oP "(?<=Pages:)\s*[0-9]+" | tr -d " ") ; sed -i "/page=$(($MAXPAGE+1))/,\${/page=/d}" ${PDF_FILE}_tex; } }
\ifthenelse{\isempty{#1}}{\small}{#1}
\input{images/#2.pdf_tex}%
}

Title:
  PDF+LaTeX incorrectly replaces \\ (two backslashes) by a newline

Status in inkscape package in Ubuntu:
  New

Bug description:
  I have an SVG file which contains text like such, the important part
  being the double backslash:

  $\sboundary f = 
  \left[\begin{array}{c} 
  \gamma_1 = [ (e^\circ, \top) ] \\
  \gamma_2 = [ (e^\circ, \top) ]
  \end{array}\right]$

  Using Inkscape 0.91 r13725, on Kubuntu 16.04 64bits, PDF+LaTeX
  converts the text to the following, that is, replaces the double
  backslashes by a newline!

  
      \put(0.50170692,0.32122315){\color[rgb]{0,0,0}\makebox(0,0)[b]{\smash{$\sboundary f = 
    \left[\begin{array}{c} 
    \gamma_1 = [ (e^\circ, \top) ] 
   
    \gamma_2 = [ (e^\circ, \top) ]
    \end{array}\right]$}}}%

  Which makes LaTeX crash with the error:

  Runaway argument?
  {$\sboundary f = \left [\begin {array}{c} \gamma _1 = [ (e^\circ , \top \ETC.
  ! Paragraph ended before \makesm@sh was complete.
  <to be read again> 
                     \par 
  l.64   \end{array}\right]$}}}
                               %

  I do need the backslashes so that the array environment knows where
  the next row starts. It seems Inkscape is trying to be too smart. In a
  previous version of Inkscape (sorry, I don't know which), this text
  used to be correctly exported as the following:

      \put(0.50170692,0.32122315){\color[rgb]{0,0,0}\makebox(0,0)[b]{\smash{$\sboundary f = 
  \left[\begin{array}{c} 
  \gamma_1 = [ (e^\circ, \top) ] \\
  \gamma_2 = [ (e^\circ, \top) ]
  \end{array}\right]$}}}%
