Ubuntu Multimedia :: K3b Does Not Burn Multisession / CD-Extra

I have a problem while burning a CD-Extra (audio+data in two seperate sessions) in k3b 1.68.0~alpha3-0ub on Karmic. The audio tracks are being burned and the session is closed, but k3b does not start burning the second session. There is the last status message in the log: "Searching previous session" and one near the progress bar: "Closing session". Normally it should close the audio session, eject the burner for resetting his state and begin burning the second session. But in fact it just stops, instead of burning the second session. My only option is to cancel.

I already tried to add -eject into the user options of wodim/cdrecord. It ejects, but it didn't help. The first (audio-)session nevertheless is correctly burned, only the second (data-)session is missing. I tried to switch the writing app to cdrdao (option in k3b), but in this mode k3b dies with a segmentation fault. Only "auto" or "cdrecord" mode works. (In fact "auto" chooses cdrecord). There doesn't seem to be a different version of k3b available in synaptic to try out. I switched over from gentoo, where k3b worked. Unfortunately I cannot remember the exact version of k3b in gentoo. The system was approx. 1 year old.

PS: Is there a native Gnome/GTK app that does CD-Extra? Brasero and GnomeBaker do not support it yet.
