In my case, a mailing-list filter hung, so I stopped akonadi, closed kmail.
kmail crashed on restart. Logging completely out is the only way to get it back into a working state.

Another possible clue: when started from the command line, I get the following warning:

me@my-pc:~$ kmail
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

Application: KMail (kmail), signal: Segmentation fault

New crash information added by DrKonqi

kmail (4.14.6) on KDE Platform 4.14.6 using Qt 4.8.6

- What I was doing when the application crashed:

KMail locked up when I tried to un-delete a message (move back to inbox from trash folder..)

-- Backtrace (Reduced):
