Unfortunately autobuilders keep on reproducing it. :-(

I have uploaded a package where I fixed the xvfb issue and did a source
only upload to make sure also amd64 will be autobuilt.  While amd64 is
fine (also regarding the xserver issue - thanks to Gregor for the hints)
the i386 build log[1] shows the

** inst
** preparing package for lazy loading
Creating a generic function for 'toJSON' from package 'jsonlite' in package 'googleVis'
Error: segfault from C stack overflow
* removing '/«PKGBUILDDIR»/debian/r-cran-treescape/usr/lib/R/site-library/treescape'

again even if the log also has gcc-6-base i386 6.2.1-6  and binutils
i386 2.27.51.20161212-1 - so the toolchain on autobuilder is the same as
it worked for you.  There might be a difference between a qemu emulation
and real hardware, thought.

Kind regards and thanks for checking anyway

     Andreas.
