Application: k3b (2.0.2)
KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-20-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

I had burned a (Linux .ISO) DVD.  After completion, I inserted the DVD, opened a terminal session and made the DVD my default directory ( cd /media/simon/Xubuntu\ 12.04.4\ LTS\ amd64/ ), checked the contents ( md5sum -c md5sum.txt ) (they were OK), exited the terminal session then, in PCManFM 1.1.2 I clicked on the Eject icon for the drive.  That is when the crash occurred.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
