akonadi_imap_resource crashed with SIGSEGV in Akonadi::CollectionFetchJob::collections()

[PhotonQyv]

I was using kmail, and wanted to re-sync my folders, it didn't seem to be working, then akonadi_imap_resource crashed, now the sync has started working again, so I can only presume I forced it to crash by my keeping requesting my mail folders to sync, when they didn't appear to be.

Perhaps a case of user impatience on my part.
