Evolution crashing - how to debug ?

[Rod Butcher <rbutcher hyenainternet com>]

I've built evolution 2.2 from cvs -r gnome-2-10. My gnome environment is 
2.11.
Evolution crashes on selecting any option from a drop-down list, such as 
selecting pop server option.
When the list (pop, imap etc) is displayed the following messages are 
logged :-
(evolution-2.2:8146): evolution-mail-WARNING **: Cannot activate 
OAFIID:GNOME_Spell_Dictionary:0.3
(evolution-2.2:8146): Gtk-CRITICAL **: gtk_entry_set_text: assertion 
`text != NULL' failed
(evolution-2.2:8146): Gtk-CRITICAL **: 
gtk_tree_sortable_set_sort_column_id: assertion `GTK_IS_TREE_SORTABLE 
(sortable)' failed
BBDB spinning up...

When I actually select an option from the dropdown list no further 
messages are output, evolution just crashes.

How do you guys actually debug something like this ? Using an unstable 
gnome is part of my learning curve.
thanks
Rod
