Insight
When an attachment file is opened in a KDE4 application, it is copied to a temporary directory and opened by a 'kioexec' process. When you close the application, the 'kioexec' process should automatically close after some minutes of inactivity in the temporary file. The kdebase4-runtime package released in Mandriva Linux 2009 has a bug which prevents the 'kioexec' process from closing.
This update fixes the problem.
