I've noticed that Gpredict crashes with a segfault when I try to open the module configuration menu after closing the antenna control. This behavior seems related to issue #279.
OS: Ubuntu 16.04.1
Kernel: 4.15.0-142-generic
CPU: Intel (R) Core i7-7576U @ 3.50 GHz
Gpredict Version: 2.3.115-0f3be
Rotator Control: Yarsu G-5500 az-el rotator with the Yaesu GS-232B PC interface
Here is how to reproduce the issue:
Open the antenna control, track, and engage
Un-engage, un-track, and close the antenna control
Open the satellite module popup and select "configure"
What I've learned so far is that gtk_rot_ctrl_timeout_cb is being called after rot_ctrl_destroy (which should have removed the corresponding timeout source from the default main context). At gtk-rot-ctrl.c:804 it attempts to access a property of ctrl->AzSet (at this point ctrl->SetAz is NULL) and segfaults.
I get the following error messages:
(gpredict:11045): GLib-GObject-WARNING **: invalid unclassed pointer in cast to 'GtkRotCtrl'
Segmentation fault
