Bug 321073

Application: k3b (2.0.2)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-23-generic x86_64
Distribution: Linux Mint 15 Olivia

-- Information about the crash:
I needed to write an iso file (approx 2.6 GB) to a DVD-R disk. The blanks are Maxell 16x DVD-R being written in an LG drive with the model number GH22LP20. I'm running Mint Linux 15 (olivia) with the cinnamon desktop and I've installed the KDE runtime so that I can use K3B. KDE was installed from the packages in  the linux mint repositories.

I ran the burn in simulate mode and received no errors. I than re-ran the burn with auto speed detection, auto mode and verify written data selected. The burn seemed to progress without error reaching 100% write complete, 50% overall. As soon as the verification started I received a warning message saying that no suitable medium was detected and that I was to load a DVD. As the medium was already loaded I was left with no option but to cancel the burn at this stage.

Following the cancellation I attempted to use the eject function from the K3B menu but the disk refused to eject. I then tried to close K3B using the close widget on the window (the x top right) but got no response. On the second attempt to close the window K3B crashed.

On reinserting the burned DVD I am informed that the medium is empty, However, examination of the surface would seem to indicate that the files were burned.
