Application: kmail (1.13.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I was replying to a message. I wanted to send it to others as well. I clicked on the Select button beside an empty To field and got a list of addresses.  I picked one from it (worked). I clicked Select a second time and KMail disappeared.  Happens every time. 

The crash can be reproduced every time.

 -- Backtrace:
