--- Comment #2 from David Faure <faure kde org>  2010-05-01 00:13:16 ---
Here's my debugging of the issue.
The problem is that the imap resource "moves on to the next task" while it
still has a KIMAP::SelectJob running. So later on when that job finishes, the
resource is quite confused and hits asserts.

The reason why the imap resource moves on to the next task is that
Akonadi::ResourceBasePrivate::slotItemSyncDone calls taskDone.
And ItemSync is done because of an error (ItemFetchJob subjob fails).
But still, taskDone is called too early, since the slot connected to that
KIMAP::SelectJob was the one that was supposed to say "itemsRetrievalDone".

I assume the running kimap jobs should be killed when ItemSync fails?
