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.
