Application: k3b (2.0.2)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: K3B crashes when adding iso file
There are no real duplicates because I'm running beta versions of kubuntu files and I update my computer with the latest updates files EVERY evening. 
If I navigate to the iso file via Dolphin and click on it, k3b opens and runs flawlessly. Once it's open, if I use k3b to navigate to the iso file and click on it, k3b will crash.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
