Re: [Denemo-devel] Denemo crash

[Richard Shann]

It would seem that this crash happens when clicking on a menu item 
(I say this because I can see

gtk_menu_shell_activate_item ()

in the back trace) before Denemo's close routine gets called.

If I'm right it would be very surprising if clicking on other menu items
worked as there is nothing special about the File->Quit or File->Close
items. 

Some questions then:
        Is the crash reliable?
        Can other menu items be invoked successfully?
        Does it happen if quit is initiated via a shortcut?

As I may not be able to respond quickly over the next couple of days,
I'll mention a further avenue of investigation here:
        If a break is set on the close_project() function (by issuing 

gdb> break close_project

at the gdb command prompt) does the program still crash on exit?
