Subject: KMail crashes when fast move mouse over folders.

X-Mailer: KMail [version 1.1.33]

Package: kmail
Version: 1.1.33

There is a bug in current KMail from the HEAD branch.
To reproduce it it is enough to switch to folders other that
inboxoutbox/sent-mail, move mouse fast over
folders list. Folders will try to switch follow mouse
and in some point KMail will crash. As it can be seen from
backtrace attached problem is that during folder select
ProcessEvents is called which call folder select again.
