[libvirt] libvirt 0.9.0 crashes on first start since boot

Hi, I've upgraded to 0.9.0 today on my Debian Squeeze boxes. Everything went fine, expect on one node (and only on that one, although the setup is identical), the first start of libvirtd since boot (and again, only that start) crashes with SEGV. Here are traces from gdb: http://pastebin.com/DiZrw0S5 http://pastebin.com/eacJRv07 If I delete the PID-file and start libvirtd again, it works fine. It doesn't seem to matter when the first start since boot happens, I've deactivated startup of libvirtd at boot time. Any ideas or further infos needed? thanks & regards, thomas
