Application: kmail (4.8.5)
KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.6-2.10-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I simply a Reply to All button and kmail rapidly display a message saying it could could not save the current something and then kmail disappears.

While lauched from a terminal it displays a message saying something related to the thread display (see below).

QObject: Cannot create children for a parent that is in a different thread.
(Parent is Nepomuk::ResourceManager(0x11c0b30), parent's thread is QThread(0xdf8260), current thread is QThread(0x169e3f0)

Funny thing it works witl all the messages except one thread of two mails. It frezzes while hitting Reply to All for one and crashes while hitting Reply to All for the other.

I presume that the person used a previous mail exchenge for sending a new mail and kmail cannot decide if the mail is within the same thread or not.

kind regards,

The crash can be reproduced every time.
