OK, thanks. I can replicate this on one machine (on which python is
compiled for 32bit)

but not on another (on which python supports 64 bit)

My guess is the transformation is putting this int out of bounds on
the 32 bit system triggering an exception in the cxx code.
>From the exception, it looks like the exception is being set in cxx
extension code but is not being raised at the time the exception is
set, because there is no reason the iteration over the info should be
triggering the exception at that time. I fixed backend agg to raise
the proper exception so it is at least less confusing -- it now raises

I'm not sure what the desired behavior here is. We could make it fail
silently (not plot the text rather than raise)....
