Bug 222196

Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.9-174.fc12.i686 i686
Distribution: "Fedora release 12 (Constantine)"

What I was doing when the application crashed:
KMail (Fedora 12 i386) crashes after sometime from the startup (about 5-10 minutes), in the meanwhile it's very slow and almost unusable. It seems to access the disk very heavily (i/o wait is high) at startup.
Sometimes KMail is able to start but is incredibly slow and crashes after some time.
I am accessing two POP3 accounts (downloading mail locally) and one IMAP account.
