Here's where I first experienced the problem.

In a long piece of code running in the notebook, the following line works:

pts.show(axes_labels = (r"$x (\mu)$", r"$y (\mu)$"), figsize = (8, 2))

I changed the 2 in the figsize parameter to 1.5:

pts.show(axes_labels = (r"$x (\mu)$", r"$y (\mu)$"), figsize = (8, 1.5))

and instead of a plot, I get

       
------------------------------------------------------------------------
Unhandled SIGILL: An illegal instruction occurred in Sage.
This probably occurred because a *compiled* component of Sage has a bug
in it and is not properly wrapped with sig_on(), sig_off(). You might
want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate.

and in the Terminal window from which I invoked notebook() is the messge:

2012-05-16 17:33:43-0700 [HTTPChannel,3,127.0.0.1] 
2012-05-16 17:36:28-0700 [HTTPChannel,3,127.0.0.1] got EOF subprocess must have 
crashed...
2012-05-16 17:36:28-0700 [HTTPChannel,3,127.0.0.1] 

The notebook keeps running and I seem to be able to exit from the notebook and 
from sage normally.

Is there a log file somewhere that provides more data?
