i found on the developer's page referring to k3b 1.1
K3b News - K3b
In the meantime enjoy this very small bugfix release which fixes three annoyances:
* Fixed CD Copy device selection when starting from the KDE "run" dialog (Bug 151924)
* Fixed HAL mounting (thanks to Ken Milmore)
* Always wait for the drive to become ready before starting verification (this should fix some of the problems with failed verification where K3b claims that no medium is in the drive.)
i think the next version will fix the issue.
