-- Information about the crash:
- What I was doing when the application crashed:

Restarted Akonadi server from akonadiconsole.
Both instances of plasma-desktop, one for each of my two X displays, crashed.
Both instances contain a digital clock widget.

KDE SC is compiled from yesterday's git master.

-- Backtrace:
