I don't know exactly, but I've seen it a lot (and it happens even if you run 
the script outside ipython, so it's not ipython's fault).  I'm pretty 
convinced it's a bug in weave.  About a year ago I tracked and fixed a similar 
bug, but it took some serious effort: the weave code isn't particularly 
simple.  Since I haven't been able to find a block of time I can sink into 
this, I've been avoiding it, unfortunately.  It might not prove to be so 
tricky with this one, so give it a go if you have a bit of spare time.
