Hi Mario,
Thanks for providing the strace.  Is it possible for you to post a
backtrace?

The backtrace shows where exactly the segfault occurs.  Try this:

  $ gdb --args path/to/qemu-nbd test.img

When the qemu-nbd process crashes you will be at the gdb prompt and can
print the backtrace:

  (gdb) bt

Please post the gdb output.

Thanks,
Stefan
