I think I mentioned this problem some time ago, but playing with ComplexButton makes it much worse (when meta charset causes a repush).

The backtrace shows that it's unhappy because IdleFunc doesn't have an equals().

To make the problem go away, I changed the remove in FltkPlatform::removeIdle() to a removeRef, but, again, I don't know this code well enough to know what should be going on.

As far as I can see it should be removeRef () here, as you suggest. While looking at it, I found a buglet in layout.cc.
