Smoke Lores not baking to disk in latest builds

Is this a bug? In latest builds (I tried 29369 and 29458 linux 64 bit from graphicall) when I create a new smoke system, the lores cache won’t bake to disk (only the hires). That results in just a static frame :frowning:

When I create the scene with an older version of blender and bake with said buils, everything works fine.
When trying to bake the scene created with the newest build using an older one, the error remains.

Can anyone reproduce this?

Just tested 29458 64bit on Mac OS X 10.5.8 and everythings working fine. Weird.

Workaround: Reload Factory Settings. Still seems like a bug to me :frowning:
