I installed the cdrecord from  for lucid and I still can't continue a multisession cd.
K3b failed writing multisession project - kubuntu 10.04 with kde 4.4.3

Writing DVD-R in incremental mode
Using wodim 1.1.10
Unmounting medium
Starting incremental sequential writing at 16x speed
cdrecord has no permission to open the device
You may use K3bsetup to solve this problem
