I had my Awasu repeatably crash (close down, no core dump or any other dialog pops up) when I selected a different channel filter through the pop-down list box on the My Channels tab of the Control Center. I normally use the "Unread items" filter, but had to check a feed which was hidden so I selected the "All" filter. I normally only ever switch between these two filters.
I fixed this temporarily by simply selecting a different filter through View -> Channel filters. After doing this, I could again switch filters through the Control Center too - a couple of times. After testing this newly working-again feature for a couple of times, I had the same end result, i.e. Awasu crashed.
I'm currently using version 2.1.3, advanced edition.
