This is indeed a bug in KMail: it calls a code that depends on event loop from KMKernel::cleanup(), which is invoked after the main event loop is destroyed (and QCoreApplication::aboutToQuit() is emitted). This hits an assert in KGlobalStatic in Akonadi::Control, but could trigger a bug anywhere. Starting a "nested" event loop after the main event loop is destroyed is IMO wrong - it should better be handled from KMailApplication destructor, or somewhere similar.

*** Bug 326562 has been marked as a duplicate of this bug. ***
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
