Exception when going to different tab
I got two messages from transport, each has been opened in separate tab and when clicking on first one, I got following exception:
Traceback (most recent call last): File "/usr/share/gajim/src/message_window.py", line 737, in _on_notebook_switch_page new_ctrl.set_control_active(True) AttributeError: 'NoneType' object has no attribute 'set_control_active'
