Here is mine, it renders fine with two blend materials but crashes using three.
Ubuntu 8.10 64 bit
Yafaray r305
(ps - I can't use .7z compression as it not an allowed file extension ? .7z - 75 kb .zip - 105 kb)

Greetings, I'm using a blend material for my product package. It's using an alpha image to control the opacity of the serrated edge near the top of the product. The first material is a shiny diffuse with 100% transparency. The second material is a Coated Glossy Material with the color diffuse product texture.The composite material uses the alpha texture map to control the transparency. It renders fine (but much slower) than a non blended material as long as I use Direct Lighting with AO and caustics. If I try photon mapping with the Blended material, Blender crashes. Thanks for your help!
I'm using Blender 2.48a for Mac OS and Yafaray 0.1.305

here is an extremly simple file: only one blend-mat, two shinydiff-mats mixed with a checker-te, crashing while render reaches the blended objekt in yafaray gui
win 32, yafaray 0.1.1

I tried your scene and indeed it crash because blend mat cannot find the blend texture (at least here because you didn't packed the texture).
By the way, addind a check to blend mat to skip faulty textures without crashing would be better user experience ;D

I also have some funky behaviour with blend material. These are my experiences so far:
- Blender crashes when I blend two materials with a texture mask (procedural or external) and both materials have a texture assigned to COL (other mappings are fine). The crash happens sometimes with the procedural texture (depending on the type it seems, I'm not sure - the behaviour is inconsistent here) and always with external image.
- It works (with texture mask) IF the first or both materials have no texture assigned to COL.
- (when the previous condition is satisfied) It does not render right if the texture mask is an non-procedural image. The target object renders with the second material, no matter the slider postion.
- If I don't use a texture mask, and just mix them with the slider, everything works fine.
These seem some nasty bugs to me. Maybe there's sometning wrong with my system?
Ubuntu 8.10 64 bit - Blender 2.49a (precompiled) - YafaRay 0.1.1 348M (compiled from source)
It would be fine if anyone with similar system as mine would try out the attached testing scene and report.
EDIT: It seems that the file was not attached. Here it is: http://www.zshare.net/download/6666521240deec47/

Hi, I have the same problem.
Ubuntu 9.10, 64bits, Intel... Blender 2.49a.
The problem occurs only when I press some Yafaray button.
Are there any logs saved?
I have a full-screen mode. I guess I should execute blender in a windowed mode, of from shell?
