Bug 169471

Version:           1.10.0 (using 4.1.00 (KDE 4.1.0), Debian packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.26-melech

Kmail crashes often after sending a mail. The mail was sent out correctly. I had no Kmail windows open at the time, just a composer window launched from a mailto: URL.

Program: Kmail (kmail), signal SIGABRT
