Re: Problem with global destruction

[Ari Jolma <ari jolma tkk fi>]

I'm getting back to this issue, since I finally got a good gdb backtrace 
and Glib NOISY log from the bug(?):

Below are three logs, the first and third are from gdb, they show that 
the SegFault may happen at least in g_signal_emit_valist () and 
g_signal_has_handler_pending (). The 2nd log shows that the segfault 
seems to happen in this case when Gtk2::Window has been destroyed and 
Gtk2::SpinButton is being destroyed (in another case  the segfault 
happens when Gtk2::ComboBox is being destroyed). The SpinButton and 
ComboBox are both widgets in a dialog that is created with Gtk2::GladeXML.

Cheers,

Ari
