The problem here was that when opening a channel, we were checking whether the channel given is alias (can't be NULL for running domain) or it's name, which can be NULL (for example with spicevmc). In case of such domain qemuDomainOpenChannel() made the daemon crash. STREQ_NULLABLE() is safe to use since the code in question is wrapped in "if (name)" and is more readable, so use that instead of checking for non-NULL "vm->def->channels[i]->target.name".

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
