Bug#702768: libgtk-3-0: Segfault in _gtk_bubble_window_popdown

[Fabian Greffrath]

Package: libgtk-3-0
Version: 3.7.12-1
Severity: normal

Hi,

recently, gedit crashes due to a segfault in _gtk_bubble_window_popdown in
libgtk-3-0:

(gdb) bt
#0  _gtk_bubble_window_popdown (window=0x0)
    at /build/buildd-
gtk+3.0_3.7.12-1-amd64-L0Jcgp/gtk+3.0-3.7.12/./gtk/gtkbubblewindow.c:1135
#1  0x00007ffff7207f4a in text_window_scroll (dx=0, dy=-522,
    win=<optimized out>)
    at /build/buildd-
gtk+3.0_3.7.12-1-amd64-L0Jcgp/gtk+3.0-3.7.12/./gtk/gtktextview.c:9104
#2  0x00007ffff720b43c in gtk_text_view_value_changed (
    adjustment=<optimized out>, text_view=0x8b0300)
    at /build/buildd-
gtk+3.0_3.7.12-1-amd64-L0Jcgp/gtk+3.0-3.7.12/./gtk/gtktextview.c:8055

Steps to reproduce: Open a rather long text file in gedit, e.g. gedit
/usr/share/common-licenses/GPL, and press Pg-Down.

$ dpkg -l gedit\* | awk '/^ii/{print $2" " $3}'
gedit 3.4.2-1
gedit-common 3.4.2-1
gedit-plugins 3.4.0-1

BTW, what's wrong in Gnome world, recently? I have never seen that much
segfaults in core applications before...
