Bug#748469: gnome-terminal: random crash when searching for some terminal font

[Vincent Lefevre]

Control: retitle -1 libgtk-3-0: 2nd search for font in the font chooser yields a large stack depth and crash

With the following[*]:

ypig:~> gdb --args /usr/lib/gnome-terminal/gnome-terminal-server --app-id my.foo.Terminal
(gdb) run

ypig:~> gnome-terminal --app-id my.foo.Terminal

[*] https://wiki.gnome.org/Apps/Terminal/Debugging with the
gnome-terminal-server path changed to the one used on Debian.

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff75bc427 in gtk_tree_model_get_valist (
    tree_model=tree_model at entry=0xdfda20, iter=iter at entry=0xd47e40, 
    var_args=var_args at entry=0x7ffffffe4ae0)

1797    /tmp/buildd/gtk+3.0-3.14.5/./gtk/gtktreemodel.c: No such file or directory.

I've attached the full backtrace, compressed since it is huge:
671 frames for the crashed thread. I'm wondering whether there
is a potentially infinite recursion.
