Burning files bigger than 2GB in k3b??

[Bruno Buys <brunobuys@gmail.com>]

   When I try to burn a dvd with a file bigger than 2GB, k3b tells me 
'There are files bigger than 2GB, enabling udf...' etc etc. The burn 
session takes a second and finishes reporting sucess, which is evidently 
wrong. Then, when I try to mount the dvd, it mounts, but there is 
nothing inside it. 'mount' says the device is mounted with udf fs 
supposedly correct.
k3b is 0.12.2.
dvd+rw-tools is 5.21.4.10.8-1

anyone help? I'm splitting files to <2GB parts, which is laborious...
