empty mp3 files when ripping with K3b

When ripping audio CDs with K3b and using file type “mp3 (lame)” all mp3 files are empty (file size=0 byte).
Also K3b tends to crash after having created like 5 to 10 empty files…
With other output formats, like wav, K3b does work nicely however.

Also it is impossible to configure the “mp3 (lame)” plugin as my own modifications/additions do not get saved - nor used (I believe).

I am running openSUSE 11.1 and installed the following K3b packages today:
kde4-k3b 1.66.0-2.pm.2.1
kde4-k3b-codecs 1.66.0-2.pm.2.1
(without de-installing the older Kde3 version of K3b before).

Any ideas?
