I think the segfault you see is probably unrelated, I cannot see it with
64 bit openSUSE, so it seems to be something different.
The error for 32bit versions exists also on openSUSE 32bit, I made a
virtual machine for it and tested quickly with the octave 3.4 from the
packman repository and then with one I compiled myself, so it is not
ubuntu specific.
It is clear that this has nothing to do with memory (the matrices are a
few kilobyte in size and the plot command is invoked on ridiculous small
vectors).

I will try to find out where this message really comes from. But I have
to say that I am really not good in understanding the source code of the
plot internals.
