KDE Platform Version: 4.4.4 (KDE 4.4.4)

-- Information about the crash:
Occasionally single-clicking on a message from the list pane will open the message in a new window, and then in the reader pane. In this specific case, I clicked the Delete/Trash icon in the message window and KMail immediately disappeared, launching the Crash Reporting Assistant. This crash has not happened before. 

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