Using dev09 build, but reproduced on dev08 as well.

Sample code:
https://gist.github.com/metalhead8816/af7a287b08bc4155457474ffbdd614a0

If you insert anywhere in the model list adapterlist updates and renders appropriately. If you remove from the end or beginning of the list it crashes.

Note: Converting to VerticalScroller + Column avoids any crashes and works with otherwise identical code.
