Re: gtkmm-list Digest, Vol 33, Issue 54



Just to let anyone know this was segfaulting due to a wrong
signal_activate() connected to a treeview.

Thanks, Paul! (he helped me)

Subject: Segfault ending the program
Dear Gtkmm team,
my program uses libglademm to load its interface in a 'CitationWindow:
public Gtk::Window' class.

It is strangely segfaulting on quit (destroying the window through 'X'
on the right corner). Valgrind output is:

Does it mean anything to anyone? I'll continue to debug, but if anyone
has a solution (or its cause :-) I would appreciate knowing.

Thanks.

Arthur
