Sentry Crash Report:

Description MD 2009-05-05 00:16:14 UTC 
Version:           1.65.0 (using KDE 4.2.2)
Compiler:          compiled by Mandriva 
OS:                Linux
Installed from:    Mandriva RPMs

Mandriva 2009.1 64 bit.  2.6.29.1-desktop-4mnb.  Sony DRU-842A burner.  k3b-1.65.0-0.alpha1.2mdv2009.1

I want to burn 4 DVD iso images (qty 4).  It burns the first disc successfully, then ejects the disc.  I load a blank disk and close the door.  The disc spins up and is detected and K3B immediately crashes.  I repeated the process twice with the same results.  If I just burn one disc at a time (qty 1), it works fine.

The crash is as follows:  The application K3b (k3b) crashed and caused the signal 11 (SIGSEGV)

There is no backtrace information available.
Comment 1 Chris Gray 2009-05-10 04:56:29 UTC 
I'm having the exact same problem - single burns are fine, but as soon as you try to burn multiple discs it fails. I managed to catch the error and have included it below:

Application: K3b (k3b), signal SIGSEGV

Comment 2 MD 2009-05-10 04:59:39 UTC 
I have new additional information.  I *can* burn multiple qty non-ISO images (create discs with lots of files) without crashing.  I have also tested > 1 qty ISO images again, and it still crashes every time.
Comment 3 Sebastian Trueg 2009-05-26 19:03:10 UTC 
SVN commit 973242 by trueg:

* iso image writing job cleanup
* Do not delete the writing job directly after it emitted the finished signal (some cleanup needs to be done)

This finally fixes
