I have encountered a segfault in Octave when plotting any graph, then clicking
on it in the window that appears.  I'm running GNU Octave 4.0.0-7 on Arch Linux
x86_64, with Mesa 11.1.2-1.

I do not think this is a bug in Octave (see
https://savannah.gnu.org/bugs/?func=detailitem&item_id=45863 where they claim
this is not an Octave bug).  I have also attached a backtrace and core dump;
hopefully these will prove useful.  (Beware that the core dump expands to
450MB!)  In addition, the crash is very reproducible, so let me know if I can
provide further data.
