Chat: Bug report in chat module on loading, unloading and reloading

[adityaomar3]

When we reload or unload and load again the chat module it throws a gtk error and segmentation fault

(mavproxy.py:13354): Gtk-CRITICAL **: 00:08:18.468: gtk_text_attributes_ref: assertion 'values != NULL' failed

(mavproxy.py:13354): Gtk-CRITICAL **: 00:08:18.468: gtk_text_attributes_ref: assertion 'values != NULL' failed Segmentation fault (core dumped)

To reproduce this bug
Start mavproxy.py
module load chat
module unload chat
module load chat

or

Start mavproxy.py
module load chat
module reload chat
