--- Comment #4 from Andre Gemünd <scroogie at scroogie.de> ---
Can't I edit a comment? 
However, to check if the device is in use k3b calls 

lsof -Fpc dev->blockDeviceName()

e.g. 

lsof -Fpc /dev/sr0

In my case, that indeed outputs all of the processes it shows in the dialog
(k3blsofwrapperdialog).
The problem seems to be that lsof outputs pipes with these parameters, which
you see when you omit the field selection parameter (-Fpc) :

$ lsof -w /dev/sr0

Does someone know by heart how to omit pipes and sockets with lsof? Otherwise I
will try to investigate tomorrow and maybe provide a patch.
