Vista - Window Photo Gallery crashes on trying to display AVI file

This is a strange one.

- Windows Media Player can play the video without problem.
- Windows Photo Gallery is displaying a preview frame of the video
- I can load explorer, double click on a jpg file in the same folder to
bring up Windows Photo Gallery and then browse to the video using the "next"
button without a problem. The video plays in Windows Photo Gallery
flawlessly.
- However, if I first load Windows Photo Gallery and then try to open the
AVI file, by either double click on it directly or by opening a neighboring
jpg and hitting "next" then Windows Photo Gallery crashes with a DEP error.
WER say a "Stackhash" fault.

I also notice that codec icons that appear in the taskbar when using Windows
Media Player (e.g. ffdshow) do not appear when a video is playing in Windows
Photo Gallery. Does Windows Photo Gallery use Directshow? It does seem to
behave differently to Windows Media Player in a number of ways.

Any help very warmly received!
