Re: Evolution crashing - how to debug ?

[Rod Butcher <rbutcher hyenainternet com>]

OK, I've run evolution with gdb and I get the following when I select an 
option such as mail server type. If I comment out line 2749 in 
gtkcombobox.c it does't get this segfault. Why would just setting 
something to FALSE cause a segfault ? No address in pointer ?
Thanks, Rod.

(evolution-2.4:5297): GLib-GObject-CRITICAL **: g_value_get_pointer: 
assertion `G_VALUE_HOLDS_POINTER (value)' failed

Program received signal SIGSEGV, Segmentation fault.
