Public bug reported:

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