Maemomm crash with Gtk::Dialog on maemo OS

[Lassi Väätämöinen <lassi vaatamoinen tut fi>]

Hi,

I was writing an app on N800 platform and came across segmentation fault when 
running a recursive static Gtk::Main::run() within the app. This happens when 
the dialog is closed and then opened again later. The Window is inherited 
from Gtk::Dialog, but when inherited from Hildon::WIndow, I got the same 
segmentation fault. The code is as follows:


	PrefWindow window(config_);
	Gtk::Main::run(window);

I use show_all() in the dialog to show all the child widgets and then when 
closing the window I use hide(). hide_all() causes crash also so this doesn't 
have any effect probably?

Debugging the app on N800 with GDB gave me following backtrace:

GDB backtrace
#0 0x402f2a74 in ?? ()
#1 0x411d44e8 in g_type_class_unref ()
 from /usr/lib/libgobject-2.0.so.0
#2 0x00001000 in ?? () at sources.h:89
#3 0x00001000 in ?? () at sources.h:89

But due to lacking knowledge I don't know where the function 
g_type_class_unref() lies. Also what is notable that I have compiled same app 
on PC (Linux platform), and on scratchbox with maemo SDK but this 
segmentation fault does not occur with these, only on N800.

BR,
-Lassi
