Comment 1 Pedro Celestino Reis Rodrigues 2013-12-09 12:28:45 UTC 
Same crash here with

debian jessie amd64

kontact                               4:4.11.3-1
libqtcore4                     4:4.8.5+git121-g2a9ea11+dfsg1-2
libc6                           2.17-97

The main difference from the reported above is that, for me, the crash seems to be not launch related. The time elapsed after launch until it crashes is variable. No human interaction is needed to trigger the crash.
Maybe it is related with periodic mail collection from the imap server.
