Details:
The segfault sometimes says:
>> graphics_toolkit('qt')
>> plot(1:100)
>> Mesa 10.6.1 implementation error: invalid target in
_swrast_choose_texture_sample_func
Please report at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa

panic: Segmentation fault -- stopping myself...

save to 'octave-workspace' complete
Segmentation fault (core dumped)
octave-4.0.0 does not seg fault. And, I think that
fairly recent builds were OK.
And, the crash only occurs if the mouse is moved
to the plot window. (No mouse click is needed for crash)
Additional plotting can be done from the
command line.
I will try to learn more, but cannot right away.
Important: graphics_toolkit('fltk') still works.
And, I just did:
>> graphics_toolkit
ans = fltk
>> plot(1:100)
>> graphics_toolkit('qt')
>> plot(1:100)
>>
which then worked OK. So, the problem has something
to do with initialization. If fltk is used first
then qt works.
