Bug 240451

Application: k3b (1.91.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Because I have not been able to burn a ripped project to CD, I attempted to delete old projects to make sure they are not taking up too much disk space, but it crashed as soon as I started to delete.

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