libvirt/src/qemu/qemu_command.c
Daniel P. Berrange 731c911ceb Fix initialization of virCommandPtr when creating QEMU argv 
If the qemuBuildCommandLine method raised an error before the
virCommandPtr instance was created, the local var would not
be initialized, resulting in a possible SEGV in the error
cleanup branch. Also add some debugging of the method params
