Description Oliver Putz 2008-10-16 14:48:02 UTC
Version:           1.95-svn (using 4.1.68 (KDE 4.1.68 (KDE 4.2 >= 20081001)), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.26-gentoo-r1

Steps to reproduce:

1) open k3b
2) goto dialog to burn a cd image
3) start burning (before md5 sum was computed)
4) When asked what settings to use (last, default, ..), hit escape
5) When in the burning screen, hit cancel and confirm the cancellation
6) see k3b (rev 868066) eject the cd and crash with the following backtrace:


k3b: burn iso image, get asked which settings to use.
1) upper right "x" has no effect
2) pressing cancel starts the burning process
---
3) cancel burn process -> k3b crashes with backtrace:
