Ok more information!

The bug appears to be related to some enqueueing of events to main Kmail window
while the pin entry is opened.

For some reason, this symptoms appear to show most when using Inbox (I test
that on gmail cached/disconnected IMAP).

Reproduce:
1. open kmail, go to inbox of cached imap like gmail
2. select message that is signed+encr
3. pinentyr opens up
4. click a lot in the window of kmail (that is now defocused), like 10 random
clicks all over the list of email in that inbox - that list is visible, but it
is defocused and is not active (since pinetry is modal)
5. cancel pinentry
6. crash!

Tested on SMP (4 cores).

This got me faster to the bugs we observed, and to some perhaps new bugs - well
other bug traces:

You just entered an invalid passphrase.
Do you want to try again, or cancel and view the message undecrypted?
