Bug 243808

Application: k3b (1.91.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic i686
Distribution: Linux Mint 9 Isadora

-- Information about the crash:
System: Linux Mint 9 LTS, Gnome 2.30.0

I finished burning a data DVD, and once K3B had run a verification scan- which turned out as unsuccessful- I ejected the DVD without closing down the program and reinserted it so that I could see if the DVD contents were accessible via Nautilus. Nautilus popped up with the DVD contents, and at the same time an error window appeared telling me that the program had crashed. 

This is the first time I have experienced this error. I will attempt further burns and see if the same happens. 

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