New crash information added by DrKonqi

kmail (4.8 rc2) on KDE Platform 4.7.97 (4.8 RC2 (4.7.97) "release 1" using Qt
4.8.0

- What I was doing when the application crashed:

I think this crash is related, too.

1.) Have 10+ dIMAP folders
2.) Expand all the folders in the left side of KMail
3.) Click and drag from upside-down: click on an empty area below the folders,
hold the mouse button, move the mouse upwards fast
4.) and while you're doing this, on the halfway KMail will crash
