-- Information about the crash:
Akonadi resources often get stuck synchronizing. One way of working around that
is to restart akonadiserver. Sometimes akonadi then crashes, as with this
crash.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Segmentation fault
