(rqt_msg, rqt_srv, rqt_action) IndexError: list index out of range

[130s]

Traceback (most recent call last):
  File "~/ROS/groovy_quantal/catkinws_sandb/src/rqt_common_plugins/rqt_msg/src/rqt_msg/messages_widget.py",
line 110, in _handle_mouse_press

IndexError: list index out of range

To reproduce,

1. On rqt_msg for example, choose actionlib/TestAction and press "+"
2. Traverse the tree to the leaf on action_goal --> header
3. Right click and choose either "View Text" or "View Raw".

1 & 2 could be other msg / attribute. Same thing happens on rqt_srv, rqt_action.

Sometimes at unknown timing, this stops happening. But the period until then ranges from 10 secs to a few minutes.

Problem was, when user right-clicks on QTreeview BEFORE her/his first left-click, selectionIndex stays 0 but the code wasn't handling that situation.
