%%%Hi Miika,
as discussed previously, here is my crasher.

- Operating System, Graphics card ---

Win7, 6GB Ram, crappy intel, i5

- Blender version with error, and version that worked ---

Error: 55587

- Short description of error ---

As the title says: Blender crashes while clicking in the timeline

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

Open the blend http://www.pasteall.org/blend/20389 and bake the smoke sim. Go to the materials tab and select the "smoke density". After that click in the timeline several times... Blender crashes

And as a second issue: The smoke density preview is not getting refreshed until I click on the timeline...when I use the arrow keys, it still stays the same until I click on the timeline - so I assume a refresh is only triggered on click and not on frame change..

Greetings, Thomas Beck

%%%This seems to be related to material preview render going on in the other thread:

Preview starts generating / rendering frame x in separate thread
Scene frame is changed
Smoke data gets changed (also volume resolution because of adaptive domain)
Preview thread is still reading old memory pointer / data resolution -> Crash

It's better someone who knows how material preview code works takes a look at this.%%%

%%%This is somewhat complicated to fix. The problem is that in this case is an exception, usually preview render just involves materials and textures but here it's also using object data through the voxel data texture. This bug is probably as old as the volume rendering code.%%%
