I can reproduce it with python-2.5 / R-2.6.1 as well.
The error might well only have to do with X11 devices only, so
I wanted to try R-2.7.0 (since it will/should be using cairo devices
by default), but no luck: I already get error a RunTime error at load
time :-/ .
On the other end, I managed to try the code in the example with a
rewrite of rpy I am working on and R-2.7-alpha: no more crashing on
the C stack, but no refresh on resize (so blank window after
resizing).
Are Microsoft Windows users observing the C stack problem ?
