Application that crashed: kmail
Version of the application: 1.12.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.6.0
Operating System: Linux 2.6.30.9-99.fc11.x86_64 x86_64

What I was doing when the application crashed:
Now, I can't remove these mails from inbox, because kmail freeze and consume all memory ( 4Gb + swap)
How i can understand the mail contains text log file with size near 1.5Mb
