KDE Platform Version: 4.4.4 (KDE 4.4.4)

-- Information about the crash:
I recently started using the KMail Spam filter with my system. To train it, I have the filter dump what it thinks is spam into a subfolder of Trash (Trash/Spam). Tonight as I was reviewing the contents of the folder (many many false positives, I'm afraid), KMail crashed when I selected a group of messages and clicked the Ham toolbar icon. 

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