Unrecoverable error: stackunderflow in .setdistillerparams

PostScript/PDF Interpreter finished. Return status 65280 executed command : /usr/bin/gs -I/home/manu/.fonts -q -dDELAYBIND -dWRITESYSTEMDICT -dNODISPLAY -dNOEPS "/tmp/inkscape-Lk7JkT/psinRKL3mZ"

The interpreter seems to have failed, cannot proceed !

This is related to bug 1218350, however, adding a wrapper around /usr/bin/gs to add -dUseCIEColor still generates the error.

Following http://bugs.ghostscript.com/show_bug.cgi?id=694066#c4 adding -dColorConversionStrategy=/LeaveColorUnchanged instead fixes it but it produces some spurious output:

Nonetheless, the rendered formula seems correct.

This could be a bug in gs, in how pstoedit calls gs, or in how inkscape calls pstoedit.

Work-around in case it were useful to someone else:
