MonoDevelop crash dump

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US)
AppleWebKit/534.7 (KHTML, like Gecko) Chrome/7.0.517.44 Safari/534.7

While trying to debug this MonoDevelop crashed (details attached), so I don't
have full details.

First, the inner exception was:
Attempting to JIT compile method
'System.Linq.Enumerable/PredicateOf`1<Qythyx.Zoing.Game.Ship/IntentionWithTime>:.cctor
()' while running with --aot-only.

IntentionWithTime in a private struct. It is relatively simple, so I've
included it and another referenced struct, Intention in the Additional
Information section.


The action code being run when the exception occurred was:
_nextIntention = (
    from interaction in interactions
    where interaction != IntentionWithTime.Empty
        && interaction.Time <= timeRemaining
    orderby interaction.Time
    select interaction
 ).FirstOrDefault();



Reproducible: Always
