Kontact/Kmail crashes too quietly

[Arthur Pemberton]

How can I get Kmail to give me something to report when it crashes?
One second I've moving an email to another folder, the next second the
window has disappeared.

I'd like to file a bug, but I can't reproduce these crashes, and have
nothing to show for them.
