I believe SVN 21805 fixes this issue. Please let me know if not.

Not fixed in r21805. Still the same crash.

I've added a few additional assertions to help diagnose the problem in SVN 21813. I still could not reproduce it (or figure out by reading code), so please report it if any of those assertions fails.

SVN 21830 contains another possible fix, found one path that conceivably might lead to an error at line 1438.
