--- Comment #10 from sombragris at sombragris.org ---
Hi, I can tell that the occurrence of this behavior reduced noticeably with KDE
4.9 final. However, it is still present. Right now I was sending an email with
a 500 KB attachment and I got stung by this bug again. Thus, I exited Kontact
and then called Kmail. It should be safe, because I exited Kontact, but no. Dr.
Konqui  promptly informed me that Kontact (which I supposedly exited
previously) crashed. This is the crash report:

Application: Kontact (kontact), signal: Segmentation fault
