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.
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 [?1034h[Thread debugging using libthread_db enabled] 0x00007f0874f8bce1 in nanosleep () from /lib64/libc.so.6 [Current thread is 1 (Thread 0x7f087e485750 (LWP 16001))] Thread 4 (Thread 0x7f0867fbf950 (LWP 16002)): #0 0x00007f0874fb6662 in select () from /lib64/libc.so.6 #1 0x00007f087d786366 in ??

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.
