Comment:

 I fixed the bug that caused the crash in `Space.hs`:
 changeset:af9e96991659185821632ff96383480c9dc9cbda

 (should be merged to 7.0.4)

 I'm optimistically assuming this fixes the original bug too.  Please try
 the 7.0.4 release candidate (when we put it out), and let us know if you
 can still reproduce the problem.
