On another run I received more information:

 *** caught bus error ***
address 0x0, cause 'non-existent physical address'

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: Exception in thread Thread-1:
Traceback (most recent call last):

File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/rpy.py", line 203, in r_eventloop
    _r_lock.release()
error: release unlocked lock

Is this a problem related to locking in R?

Any ideas as to what is causing this and how to fix?
