Tested on:
windows 7
geforce gtx 660 ti

Also tested:
windows 7
geforce gtx 670

Broken: Blender 2.73a official

Animated image textures in cycles material viewport mode are buggy and extremely finicky to the point of being almost unusable.

Here's a zip with a .blend and 5 clearly numbered images to demonstrate:
image_plane_anim.zip

There are multiple problems, and they may originate from the same bug. Here's what I've found so far:

Pressing play does not update the image, only scrubbing the timeline or alt-scroll up/down affects it.
Repeatedly scrubbing the timeline from frame 0 to frame 5 will eventually cause a permanent pink image in the viewport.
Using alt-scroll up/down in the viewport will often show the incorrect image. For example, sometimes going to the previous frame will show the next frame's image. (Viewport not being redrawn after frame change?)

If everything was working properly, the number on the plane in the 3d viewport should be the current frame number.

Yes, material method is buggy, works fine in render mode.
Also, if the number is not displayed correctly, if one clicks on the texture node, it updates correctly.
Maybe autorefresh timing is off?

Antony, could it be an OpenGL issue?

Would have thought of a missing update event, but the fact texture remains invalid (pink state) even when editing its settings makes me eye to OGL…

Generally animation of values + GLSL + play real-time animation is not working so well. It forces recompilation of shaders and we avoid that for speed. That said, it's weird that we get pink images so I'll take a look here later.
