I’m using Blender 2.37 with Yafray on Ubuntu Linux. Blender just keeps stopping, and says:
/usr/bin/blender: line 46: 30787 Segmentation fault blender-bin $@
Any ideas??
Not a single one, huh? Damnit. 
Perhaps version 2.40 works better? Or if you wait for a while, you could test out 2.41 or orange build. You can get orange build from http://www.graphicall.org/builds/index.php
It appears to be a Yafray problem…I’m shifting over to their forums. Thanks anyway
