KDE Platform Version: 4.4.4 (KDE 4.4.4)

-- Information about the crash:
I started to move several emails from a google imap account to a local pop3 inbox. Each move was done by drag&drop. Since the emails were quite large (3-22MB) the first job did not finish before I dragged the other two. While Kontact was moving the emails it suddenly crashed.

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