I don't know what to say.
When I use these commands here, I don't get a segfault and I
get a perfectly usable TeX file.  

Tested both with 4.2.2 and with current CVS.

Could you run this under a debugger, or via strace, or even
valgrind, so that we can find out where the segfault happens?

Also the versions of cairo/pango/etc might be relevant.
What is the output of  ldd `which gnuplot` ?

That looks like a legitimate error message, though.
Do you in fact have gnuplot.cfg installed somewhere that
LaTeX knows about?
