Application: kmail (1.13.3)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-3-686 i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
I wanted to write a message to many recipients. From the message composition window, I pushed the "select" button, and selected a few addresses. Then I realized I want the addresses to be BCC, so I canceled the picker, changed to "BCC", and pressed "select" again. KMail crashed.

 -- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
