Comment 12 Cole Robinson 2014-06-02 15:35:48 UTC 
Latest f20 gives a clearer error here:

qemu-system-x86_64: -cdrom /home/crobinso/NetBoot9.dmg: sector count 222056 for chunk 1877 is larger than max (131072)
qemu-system-x86_64: -cdrom /home/crobinso/NetBoot9.dmg: could not open disk image /home/crobinso/NetBoot9.dmg: Invalid argument

It doesn't crash, so closing. But maybe qemu's dmg support can't handle old images
Comment 13 Peter Wu 2014-12-27 09:38:22 UTC 
For your information, QEMU cannot accept this image because it uses the older Apple Data Compression (ADC) format. If someone wants to implement it, have a look at the format described at http://www.macdisk.com/dmgen.php

dmg2img has an implementation for the decompression routine: http://vu1tur.eu.org/tools/
