Bug#894373: blender: Assertion Non-finite sum in path_radiance_clamp_and_sum failed

[Lars Schimmer]

Package: blender
Version: 2.79.a+dfsg0-2
Severity: normal

Dear Maintainer,


Blender dies with error: blender:
/build/blender-AiaOIi/blender-2.79.a+dfsg0/intern/cycles/kernel/../kernel/kernel_accumulate.h:514:
ccl::float3 ccl::path_radiance_clamp_and_sum(ccl::KernelGlobals*,
ccl::PathRadiance*): Assertion `!"Non-finite sum in
path_radiance_clamp_and_sum!"' failed.

zsh: abort      blender -b -y Glass\ Tris\ VR\ 2\ anim.blend -noaudio
-nojoystick -o render_

Upstream 2.79b from blender.org does work without that problem on the
same machine.

If needed I can supply the .blend file (90MB)
