I've been testing it a little bit and I found a problem. The error
reporting does not work in all the situations. If you want to check it,
just comment the second call to tny_account_store_get_accounts in the
demo UI (and the gtk_combo_box_set_model). Then open the demoUI, and
click in the "Go online" button, then when prompted for a password,
press Cancel and then the alert dialog won't appear (it did with the
code uncommented).

I studied it for some time but I couldn't found the error. The point is
that in the first call to tny_account_store_get_accounts, the
camel-session is not able to found the provider's services

<code at camel-session.c get_service>
/* Now look up the service in the provider's cache */
service = camel_object_bag_reserve(provider->service_cache[type], url);

so it constructs them all. The CamelSession was previously set as online
so the disco stores are created with status CAMEL_DISCO_STORE_ONLINE.
Then when the TnyCamelAccount calls camel_disco_store_set_status this
function will exit without doing anything because the status is online.
But it won't return any error so the function
foreach_account_set_connectivity won't call the alert message.

Well, it's not easy to understand my words, it's better just to debug it
. Maybe some lock is needed.


PS: find attached a patch that initializes a field. Without it a SIGSEV
is issued sometimes. And there was a variable that was incorrectly
initialized IMO.

PS2: sorry for this ultra-dense-super-technical email :)
