Bug#757010: [libgtk-3-dev] libgtk-3-dev GtkTreeView signal callback button-press-event bug

[Cactus]

Package: libgtk-3-dev
Version: 3.4.2-7
Severity: normal
Tags: patch

--- Please enter the report below this line. ---
I create object GtkTreeView with the type of storage GtkTreeStore.
Then connect to GtkTreeView signal handler button-press-event.
In this event handler is called, but there is no selection line.
If I attach a handler to the signal button-release-event, then the 
handler is called, is an selection of the line, but fails to deploy a 
substring by pressing [+]
No errors in stderr.
The letter attached pieces of source code.
