During scrolling

[greyson]

The items in question have images being loaded with UniversalImageLoader, it appears that StaggeredGridView is having trouble recycling views.

I'm getting the following while scrolling through a long "list" of items -- certainly when there is only one column, but this may also be more systemic:
