When running the command Extensions->Rendering->LaTeX and typing in any LaTeX expression, I get no output and Inkscape returns:

               removed in the next version. For now you can restore

               the behaviour by using -dREALLYDEALYBIND but if you

Using the extension Tex Text yields a similar error:

I suspect this is a bug in the respective Inkscape extensions for LaTeX output.

System information:
macOS 10.13.3
Inkscape 0.91
pdfTeX 3.14159265-2.6-1.40.16 (TeX Live 2015)
