Ok so here is one instance when I go the videos library. I use info wrap as the view. If I hold down an arrow key it will scroll fast for a few seconds then just dies or crashes to the desktop. This is the svn21248. This does not happen with the original mediastream skin.

It seems like it died while trying to make a thumbnail for an existing entry that didnt have one. <-- This is not correct. It does the same thing even with the option to make a thumbnail is not checked.
Another Edit: This does not happen in svn21223. I cant get it to crash with this subversion.
