[Gretl-users] plot gui error

Hi: After creating a scatter-plot, I go into plot controls, select add line and enter "2*x". Gretl crashes as soon as I select OK or Close. Here is the console output: (gretl_x11:11396): Gtk-CRITICAL **: gtk_spin_button_get_value_as_int: assertion `GTK_IS_SPIN_BUTTON (spin_button)' failed get_png_bounds_info(): failed *** glibc detected *** /opt/gretl/bin/gretl_x11: double free or corruption (fasttop): 0x096d3538 *** Also, I noticed during translation the entry regarding confidence bands. How do I reach this function? Is this available for a regular OLS regression?
