I was running qemu-iotests 030 on a development branch that had a bug
that made qemu segfault. This should result in a logged 'qemu received
signal 6' message, but only prints the logging error now. The same kind
of problem affects all Python-based tests in the tree, git grep didn't
find any that initialise the logger manually.

In order to reproduce, you can fake such a crash by inserting an HMP
command like 'qemu-io ide0-hd0 abort' somewhere in a Python-based test.
