+I can't duplicate the crash (SIG*) on my box. However if I wait a long
+time (like lunch) I can get an exception (but no crash) in
+FillRectangle. Looks like something in SWF gets garbage collected.
+
+Unhandled Exception: System.ArgumentException: Invalid Parameter. A
+null reference or invalid value was found.

+As for the crasher please run under valgrind and attach the log. This
+may get us some clues about the problem.
