Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

all with error
Crashing regularly on render (often every frame or two) - freestyle and BI with toon shader.
Tried switching off freestyle in render panel, crash persists.
Also tried removing toon shaders, crash persists.
Seems to crash during transition from one frame to next during render.
Scene has driven object visibility/renderability, but crashes don't seem to correlate with keyframes afaik.
Open .blend in test folder
Have only been able to test on my machine.
Best case I've had is about 10 frames rendered before crashing, but usually one or two. Never seen this before these versions, but only now learning freestyle. Not sure if this is related.
Below is example OS crash log in case it helps:

Changed status to: 'Open'
%%%Edited report to include link to crash log, for readability.%%%
%%%That's an interesting case here!
First: tips for how to survive this file, so you can keep working on it:
in Render buttons, Performance panel:
With the above instructions renders go much faster and will be stable.
For Brecht: the crash then goes to:
rogram received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000045455246
0x0000000100fc0c30 in GPU_framebuffer_texture_detach (fb=0x45455246, tex=0x10967b0f8) at gpu_extensions.c:880
880 if (GG.currentfb != tex->fb->object) {
(gdb) where
4 0x0000000100012a91 in wm_draw_update (C=0x106a289c8) at wm_draw.c:805
The image name = "IMTex_CWHead_UV01, I don't know why it would crash though... but also not why it should be freed during render?%%%
%%%Fix in svn, thanks for the report.%%%
Changed status from 'Open' to: 'Resolved'
%%%Thanks for your help as always Ton and Brecht.
As predicted much better behaviour now. I was wondering where those .exr files were coming from. Hope my mistake has at least contributed to future fool-proofing of Blender :)%%%
