Bug 198893

Application that crashed: kmail
Version of the application: 1.12.0
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.2
Operating System: Linux 2.6.24.7 i686

What I was doing when the application crashed:
When I open a message with an attachment and press reply the new composer opens. I then press send for the first time - this press is ignored. Pressing send for the second time sends the message (successfully most of the time, sometimes it stays in the outbox) but shortly afterwards kmail crashes. 
To avoid I have to enter some characters in one of the recipient fields (BCC, CC, TO) and wait for a completion to happen.
