Some of the ReiserFS developers gave a similar reaction to some of my bug
reports. ReiserFS wasn't the most robust filesystem.
I think that it should be EXECTED that a kernel will have to occasionally deal
with filesystem images that are created by hostile parties. Userspace crash
and kernel freeze is not a suitable way of dealing with it.
