Intermittent crashes

[jagot]

Every so often, a simple script like

using Blender
using GeometryTypes
using FileIO
using AffineTransforms

Blender.clear_objects()

b = load("bunny.obj")
trf = tformscale(15.f0,3)*tformrotate([1.f0,0.f0,0.f0], Float32(π)/2)
ob = Blender.add(b, "bunny", trf)
println(ob)

Blender.render("/tmp/bunny")

crashes horribly with backtraces of this kind:
