Description of problem: Wanted to simulate writing to a DVD. Half way through the exercise, I cancelled the simulation run. K3B did not cancel right away, but eventually it did. I then tried to do a full write with verify, and K3B essentially returned to the Simulate operation. After a logout and a return (login), K3b was still acting up. It took a reboot to clear K3B problem Version-Release number of selected component (if applicable): Environment is fc5 SMP 2174, with Intel 930 cpu, Intel Mother board, and 1 gig memory. How reproducible: Read problem statement Steps to Reproduce: 1. Start ISO burn of a dvd in simulate mode 2. Part way through simulate mode, do a cancel 3. start K3b in expected "burn iso dvd mode" Actual results: K3B returns to simulate mode and will not exit from it. Could not logout, and had to reboot. I could have logged in text mode and could have done a kill -9, but chose to reboot. Expected results: Expected K3B to refresh itself, clear buffers, alloc'ed memory, pointers, and restart as if it was the first initiation after a boot. Additional info: Iso Image checksum should be verified during simulation run.
