Thanks, that helped (I’m on i386, but it’s apparently an mi bug).
I filed this as: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756376
Crossreferencing on both sides.

Haha… submitting this, I get:
An unexpected error occurred. This could be a temporary problem, or some code
is behaving incorrectly. If this problem persists, please email this page to

It looks like I got this issue too, but it looks like I got a better backtrace:

--- Comment #5 from didi.debian at cknow.org ---
Tried to report it with KDE's bug reporting assistant (BRA), but got an error.
Anyway, this was the additional info the BRA provided (backtrace was the same
as already reported by me):
Application: kontact (4.12.4)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.14-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)
-- Information about the crash:
- What I was doing when the application crashed:
Tried to start Kontact and it crashed immediately.
Sune on #debian-kde asked whether it was the same report as this one and it
surely looks like it. Already posted the backtrace, but now doing it again with
KDE's Crash Reporting Assistant since it may provide some more info.
Starting KMail standalone worked, as in it didn't crash immediately. Haven't
really used it though as in sending a mail or sth like that.
The crash can be reproduced every time.
--- Comment #6 from didi.debian at cknow.org ---
downgrading libkontactinterface4 to 4.12.4-1 fixed the issue for me too.
Got the same issue on this bug tracker as in comment#3 LOL
--- Comment #7 from didi.debian at cknow.org ---
Apparently the bug was introduced in commit
9122c2841ea25abd598308f6b8c3c303e6f74570
--- Comment #8 from Pali Rohár <pali.rohar at gmail.com> ---
Looks like commit 9122c2841ea25abd598308f6b8c3c303e6f74570 should be reason for
crash. It adds new virtual function which modify virtual table for all objects.
So it changes ABI of KontactInterface::Plugin class.
I can confirm this crash. When I use kontact from kdepim KDE4.4 compiled
against kdepimlibs KDE4.4 and upgraded kdepimlibs to KDE4.14, then I see same
crash.
I think that kdepimlibs should be backward compatible and should not change ABI
without increasing MAJOR version.
Commit 9122c2841ea25abd598308f6b8c3c303e6f74570 increased just PATH version,
which broke ABI compatibility...
CCing Montel Laurent who is author of that problematic commit. Can you comment
to this bug?
