I rarely use k3b (it upgrades more often than I run it), so I can't be sure this is first version in portage with this bug. I think I've used 2.0.0 to write one DVD, and I'm sure I've used 1.92.0_rc3 a lot and it works fine. So. When I run k3b, it immediately crash. Console output: KCrash: Application 'k3b' crashing... sock_file=/home/powerman/.kde4/socket-home/kdeinit4__0 <unknown program name>(17444)/: Communication problem with "k3b" , it probably crashed.

Please report this upstream at bugs.kde.org and add here a link to that bug report.
Actually this segfault can be fixed simply with: paxctl -m /usr/bin/k3b so please add paxmarking into ebuild. Real issue is PaX become less verbose in latest versions. Previously all segfaults which happens because of hardened was ease to detect by looking in kernel logs. But this segfault doesn't listed in kernel log at all, so it's harder to find out it happens because of PaX.

Did the pax or grsec log show anything? It start fine for me. Do strace show anything?

Having an "emerge --info k3b" would be very helpful, I think your culprit is ffmpeg ;) Zorry it is an x86 system
