Crash in dialog_file_access.c (was Re: Trouble compiling)

[Phil Longstaff]

List being null isn't the problem.

"list" isn't used until after that point in the code (it asks qof for the list of registered backends and doesn't add combobox entries for "sqlite3", "mysql" or "pgsql" if there isn't a registered backend, and the libdbi backend doesn't register a backend if the dbd file isn't present).

Same (rev18012) here on windows:

From gdb in my crash, I get:

Breakpoint 1, gnc_ui_file_access (type=1) at dialog-file-access.c:234
234g_object_connect( G_OBJECT(faw->cb_uri_type), "signal::changed", cb_uri_type_changed_cb, NULL );
(gdb) info local

ds_node = (GList *) 0x1897e68
op = (GtkButton *) 0x5c09078
align = (GtkWidget *) 0x5c0a958
fileChooser = (GtkFileChooserWidget *) 0x29b4110
fileChooserAction = GTK_FILE_CHOOSER_ACTION_SAVE

node = (GList *) 0xbfffd800
uri_type_container = (GtkWidget *) 0x5c060d8
__PRETTY_FUNCTION__ = "gnc_ui_file_access"


list is NULL, so that's probably the cause of my crash. Any suggestions on changes I can try to work on the lack of "list"? 

I have all three libdbi drivers installed, and configure reports that gnucash is configured for the dbi backend.
