KDE Platform Version: 4.4.3 (KDE 4.4.3)

Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I first tried to choose the recipient by typing in the first part of the name and waiting for completeion. Nothing happened except for the mouse symbol changing to an hourglass (or whatever the busy animation is in KUbuntu). After nothing happened for a while, I chose the select recipients button. After the dialog opened, I typed the first part of the name into the search box and KMail crashed.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
