Details:

Example:


a = zeros(2);
imagesc(a)
print('a.pdf')


returns


octave-gui: ../../../../src/mesa/vbo/vbo_exec_draw.c:278: vbo_exec_vtx_unmap:
Assertion `exec->vtx.buffer_ptr != ((void *)0)' failed.
panic: Aborted -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
octave exited with signal 6


I get the same error for other formats (png, jpg,..) and also for *saveas*. I
can however use *imwrite*.
The error also occurred after updating GNUplot from 4.6 to 5.0.2. I am using
Ubuntu 14.04.
