Starting with this commit, "Paste from LaTeX" no longer seems to work
for me. I get the following in the terminal:

  Creating file /tmp/lyx_tmpdir.sJMMXUAnpRwt/Buffer_importStringMMGtph.lyx
  Cannot read layout file `'.
  Error: Could not load module "-f".
  support/Systemcall.cpp (306): Systemcall: 'tex2lyx -fixedenc utf8 -c "article" -m "" -f "Buffer_importStringMMGtph.tex" "Buffer_importStringMMGtph.lyx"' finished with exit code 1
  Error: Cannot convert file
  ----------------------------------------
  An error occurred while running:
  tex2lyx -fixedenc utf8 -c "article" -m "" -f "Buffer_importStringMMGtph.tex"
  "Buffer_importStringMMGtph.lyx"
