I'm encountering a problem with graphics_array and latex use in plots.
The following command works fine
p1=plot(x^2, (x, -pi, pi), color='blue')
G=graphics_array(((p1,p1),(p1,p1)))
G.show(figsize=[8,8])
But if latex code is added to the plot legend it produced and error
p1=plot(x^2, (x, -pi, pi), color='blue',legend_label="$\frac{\partial
f}{\partial x}$")
G=graphics_array(((p1,p1),(p1,p1)))
G.show(figsize=[8,8])
Traceback (click to the left of this block for traceback)
...
KeyError: 'pop(): dictionary is empty'
What exactly is the problem here and is there a workaround? Is there
any alternative way to give plots individual titles in a
graphics_array?

Actually, to correct myself, it appears that the problem is not latex
in the legend label, but the mere presence of a legend label at all.
The following still produces an "pop" error
p1=plot(x^2, (x, -pi, pi), color='blue',legend_label="f")

Pop legend. There has to be a joke in here somewhere...

Anyway, this must be related to http://trac.sagemath.org/sage_trac/ticket/10244.
We just didn't do the same thing to GraphicsArray. This is now
http://trac.sagemath.org/sage_trac/ticket/11160
Thanks for the report!

This works for me:
p1=plot(x^2, (x, -pi, pi),label="f")
G=graphics_array(((p1,p1),(p1,p1)))
G.show(figsize=[8,8])
