I suspect it is another ConcurrentModificationException. My patch
improved it but doesn't solve the problem. We are editing structures
when we get responses from the server, and in another thread drawing
using the data. I am currently using a nasty hacked client where I catch
the exception when copying the collection and just try it again. This
isn't the ideal sollution so I haven't submitted a patch. Ideally we
should have all modification of these structures via well-defined
methods that can be synchronised.
