Akonadiserver crashing frequently

[Frank Mehnert <frank.mehnert@gmail.com>]

Hi,

I assume I suffer from this bug:

  https://bugs.kde.org/show_bug.cgi?id=367846

and I provided a backtrace as requested there. I observe these crashes
for a few days and they drive me crazy (running up-to-date Sid).

Now I would like to bit the bullet and recreate the IMAP accounts and
recreate the Akonadi database as mentioned in the above bug:

  ".. seems to be resolved for me after deleting all imap accounts in KMail,
   then dropping and recreating the akonadi database, then recreating the
   imap accounts. Since doing that I've not seen KMail2 lose connection to
  the akonadi server."

Deleting + re-creating the IMAP accounts is no problem but how to drop +
recreate the Akonadi database?

Any help is welcome, getting desperate :-(
