I could be wrong...
But it looks like something I've seen in parts of our plugin that redraw
a lot. But there's some race condition to get it to happen. It does seem
fairly innocuous though since if it causes any "real" error, doing
anything to redraw the image (eg changing slice) fixes it. I'll see if I
have the print of the exception anywhere. BTW this happens for me with
ij 1.42o and java 1.6.0_11
