Control: reassign -1 qemu
Control: retitle -1 qemu-img create -f qcow2 ... segfaults on mips

The problem occurs only on mips, not on mipsel. This may be an endianess
problem, I'm going to have a closer look.

I can reproduce it on one of Debian's mips porterboxes. It happens when
generating qcow2 images, apparently regardless of size and options.

I agree.
